Ecology is the branch of biology that deals with the relations of organisms to one another and to their physical surroundings. An ecological unit composed of a group of organisms of different species occupying a particular area, usually interacting with each other and their environment is called community. Population is the group of organisms of one species that interbreed and live in the same place at the same time. A species is best described as the largest group of organisms in which two individuals are capable of interbreeding and producing fertile offspring. An ecosystem is made up of plants, animals, microorganisms, soil, rocks, minerals, water sources and the local atmosphere interacting with one another. The seasons are …show more content…
Immigrate is to come in to another country to live permanently. An ecological niche is the role and position a species has in its environment; how it meets its needs for food and shelter, how it survives, and how it reproduces. A species' niche includes all of its interactions with the biotic and abiotic factors of its environment. Biotic factors are living things, while abiotic factors are nonliving things. It is advantageous for a species to occupy a unique niche in an ecosystem because it reduces the amount of competition for resources that species will …show more content…
Most communities include various populations of producer organisms which are eaten by any number of consumer populations. The green crab, for example, is a consumer as well as a decomposer. The crab will eat dead things or living things if it can catch them. A secondary consumer may also eat any number of primary consumers or producers. This non-linear set of interactions which shows the complex flow of energy in nature is more easily visualized in the following diagram.In a food web nutrients are recycled in the end by decomposers. Animals like shrimp and crabs can break the materials down to detritus. Then bacteria reduce the detritus to nutrients. Decomposers work at every level, setting free nutrients that form an essential part of the total food
In other words, a fundamental niche is where an organism can use all the resources (food, shelter, light, etc.) it needs to survive and reproduce without the interference from other species. This takes ideas from Elton because it states that food is an important part of a niche. However, Hutchinson also introduced the realized niche, the actual niche that an animal is restricted to because of outside forces such as predators and competition (Hutchinson, 1957). This is similar to Grinnell’s idea because the California Thrasher could live outside the chaparral zone because it has a diverse diet, but its realized niche is the chaparral zone because it is restricted there because of predators. Because of this, niches aren’t easy to define in nature because scientists can figure out what the ideal niche would be for an organism but multiple outside forces can make it difficult to determine its realized niche. In recent years, niche theory has not been restricted to ecology and in fact can be applied to cancer research. Studies have found that stem cells differentiate into cancer stem cells causing Cancer in
A. Define the Problem Natureview Farm, Inc. (Natureview), a small yogurt company founded in 1989, produces and markets yogurt using natural ingredients and a distinct manufacturing method that yields a smooth, creamy texture without adding artificial thickeners. As a result of this emphasis on natural ingredients, the brand has established a reputation for high quality, great tasting yogurt and is the leading natural foods brand of refrigerated yogurt. Natureview’s yogurts – available in twelve flavors in 8-ounce cups, four flavors in 32-ounce cups, and multi-pack yogurt products – are distributed nationally and the company shares leadership in the natural food channel. In 1999, the company’s revenues grew from $100,000 to $13 million; however, despite Natureview’s success and well-established brand, the company has long battled to preserve a steady level of profitability. In 1996, Jim Wagner was hired as chief financial officer and was able to successfully achieve steady profitability for the company.
Since energy is a necessary part of how an organism survives, how it obtains it’s energy is crucial. When you look at an ecosystem, and all the organisms living within that ecosystem, you can link many of the species together by their dependence on each other. Scientists will look at these links to see how they depend on each other, or in other words, where their main source of energy and nutrition is. Once that step is determined, scientists will assign that group of species to a trophic level; to either the primary producers, primary consumers, secondary consumers, or the tertiary consumers.
How does the vegetation surface type affect the amount of runoff? Speculate why this happens.
A population is a group of species that live, interact, and interbreed in a geographic area. Intraspecific competition occurs when resources, which are necessary for a population, are limited and the individuals of the same species have to compete to survive. The Tribolium species reproduce at a rapid rate. The female lays 400-500 eggs that go through metamorphosis and within a few days, those adults are sexually mature and continue the reproduction process (Calderwood 1961).
In 2003, Palmer Jackson, Inc. created a new line of sports beverage called Green Ox. This beverage has some differences from other similar beverages, as it contains the benefits of antioxidants and it can compete in more than one category, such as sports drinks, vegetable juices, and antioxidant supplements. These are not the only advantages of Green Ox, because some reputable reports argue there is a strong link between using the vitamins and minerals that Green Ox has to reduce the risk of some specific types of cancers, and Green Ox will launch on a type of market that is growing to 15% per year. In order to ensure the success for Green Ox, the company has contracted with Marketing Studies Incorporated (MSI) to study the market and do some important researches. However, Palmer Jackson, Inc. faced one of the challenges that has been common when companies prepare to launch new products on the market. First, the company needed to determine the target audience, especially as we know the large variety of people who deal with this kind of product. Second, the company needed to think thoroughly about how it could position Green Ox with its benefits on consumers’ minds, as Green Ox has the capacity to compete in three different
Ecosystems can be as small as a tide pool or a rotting log or as large as a body of water, forest or desert. Each system can consist of a community of plants and animals and this community is sustained by raw materials, chemical elements and water. Each community is surrounded by soil, water, climate and other conditions of the environment. An example of an ecosystem is a pond it supports a community of fish, frogs, insects and plants. Basic food is small organisms and plankton for the fish to consume. If the ecosystem does not maintain a balance it can weaken and the species will suffer. The systems are affected by fire, disease and severe climate changes not including predators and man such as building, pollution and mining.
You have taken a lead teacher position in a preschool program. A parent asks you to explain the program’s constructivist philosophy.
Fig.3-This food web shows that Pandas are prey to jackals and leopards. Photosynthesis is the beginnings of the food web as it produces the energy to help plants grow, which are the primary producers as highlighted in green. The Panda comes under the secondary consumer, as it uses photosynthesis to produce its food- bamboo. Cubs become a prey to other animals such as leopards and tigers which are known as the apex consumers. Decomposers listed on the right include bacteria and fungi which break down dead plants and animals.
“Modern man does not experience himself as a part of nature but as an outside force destined to dominate and conquer it. He even talks of a battle with nature, forgetting that if he won the battle he would find himself on the losing side” (E.F. Schumacher, 1974).

When we sit in a science class, most of the time we are bored as bored can get. We really do not get a chance to explore on our own to find out what’s really out there. Teachers sometimes are not able to get in depth outside the textbook because they are required to teach that all in the year. That is why a lot of kids do not really get into science because they are stuck to the book all the time. Some kids love science and do not really care about the work they have to do. Environmental science, is more than the book really says.
The branch of science that deals with how living things, including humans, are related to their surroundings is called ecology . The Earth supports some 5 million species of plants, animals, and microorganisms. These interact and influence their surroundings, forming a vast network of interrelated environmental systems called ecosystems. The arctic tundra is an ecosystem and so is a Brazilian rain forest. The islands of Hawaii are a relatively isolated ecosystem. If left undisturbed, natural environmental systems tend to achieve balance or stability among the various species of plants and animals. Complex ecosystems are able to compensate for changes caused by weather or intrusions from migrating animals and are therefore usually said to be more stable than simple ecosystems. A field of corn has only one dominant species, the corn plant, and is a very simple ecosystem. It is easily destroyed by drought, insects, disease, or overuse. A forest may remain relatively unchanged by weather that would destroy a nearby field of corn, because the forest is characterized by greater diversity of plants and animals. Its complexity gives it stability.
Social ecology is the conceptual principles for knowing the outcomes and relations of the many diverse individual and environmental factors. Social ecology is defined as the study of people within an environment, which have influence on one another. It’s believed to be the earth’s societies reflection upon itself, exploring, discovering, and considering its future (Gutkind, 1974). Factors of social ecology may include the infirmities of age, an increase of population, natural disasters, technology and the growth of society. Within social ecology it is important to notice which people are unable to see the environmental crisis. This movement is placing all the responsibility for destroying the earth on humans as they are overpopulating the planet. There is no possible way of convincing all humans to change their way of life (Bookchin, 1995). However, rather have humans distinguish and eliminate previous forms of control and destruction (Bookchin, 1995). The main standard of social ecology is the fact that problems occur from inherent social issues (Dogan, Rokkan, 1974). These problems cannot be understood without acknowledging the social issues. The development, of certain technologies, social characteristics, cities and science all has caused a vast majority of problems to the earth, which leads back to humans.
Environmental studies is a paramount field to focus on for both the present day and the future. This field of studies pertains to all people, animals, plants, and biomes around the world. Environmental Studying is important because it is only by understands the environmental processes that we can begin to take the steps necessary to correct the on-going damage that is occurring, and ultimately protect and sustain life on the planet. Unless steps are taken to try and abate and control environmental problems, which are often human-generated or exacerbated, then the environmental that we live in will continue to deteriorate. There is no life without protecting the source that sustains us. Even though I have only been alive for seventeen years, it has been long enough to see many negative environmental changes. Since I was born that population has grown by over one billion people causing deforestation, loss of wildlife, increased pollution to both air and water, and even superbugs. However, I have also been able to see extremely positive results such as an increase in the research and implementation of renewable resources. The reason I am so motivated to study environmental science is because I know that change is possible. Those who study environmental science and study have the ability to help reduce, and possible reserve, some of the damage that has been done to the environment while at the same time, helping to advance the well-being of our fellow humans.
