Ecosystem
The more one observes the world, the more one will realize that everything in this world is connected somehow. Everything and every one in this world, is part of one or more systems. An ecosystem is a complex set of relationships between living and non-living organism and their physical environment. Ecosystems vary in sizes and the living and non-living organisms that make them up. Ecosystems contain biotic factors such as plants, animals, and other organisms and also abiotic factors, such as rocks, temperature, and humidity (Coniferous Forest). Often times, ecosystems are divided into different categories based on climate patterns, soils types, and the animals and plants that inhibit them
One example of an ecosystem is the coniferous forest. Coniferous forests are generally found in the far north within the Arctic

The Sunlit zone is the outer top layer of the ocean, which gets the most sunlight and provides energy to organism through photosynthesis. About 90% of the oceans life lives in this layer (Ocean Zones). Next is the Twilight, which is the middle part of the ocean. Since too little light reaches in this layer, animals in this layer have adapted to living with little sunlight by producing their own light. Lastly, the moonlight zone is the darkest part of the ocean.
Lastly, another example of an ecosystem is my neighborhood. In my neighborhood, there is a wooded forest area where plants, animals, fungi, bacteria, and humans al interact with one another. The plants in that forest capture energy from the sun and convert it into chemical energy that animals can feed off. The animals in this ecosystem are cows, birds, insects, and bugs. These animals rely on the plants for shelter, food, and energy. Once these animals and plants die, bacteria and fungi decompose them and the cycle of life repeats
a.) Choosing organisms from four different trophic levels of this four web as examples, explain how energy is obtained at each trophic level. 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.

There’s wet tundra, alpine tundra, glaciers and iceland, coastal western hemlock/ Sitka spruce forest, and post-glacial meadows and thickets. As for marine ecosystems, continental shelf, wave-beaten coasts, and fjord estuaries have been
Purpose: The purpose of this lab is to investigate the various components of different ecosystems in a smaller representation and study the conditions required for the ecosystem’s sustainability as well as the connections between
Keystone species are such species that has an excessively large effect on its environment relative to its abundance. Such species are described as playing a critical role in maintaining the structure of an ecological community, affecting many other organisms’ inane ecosystem and helping to determine the types and numbers of various other species in the community.
The ecological framework is sometimes referred to as the ecosystems perspective; however, both concepts were generally alike and sought to answer the same question: How does one’s environment affect their behaviour in any given situation? This perspective puts the responsibility on gaps between persons and environments, rather than just on the environment alone or by simply labelling
An ecosystem is a difficult thing to define, namely because they vary so much. There are tundras, plains, mountains and so on, and there are individual ecosystems within each one, depending on geographical location, weather/climate and even the time of year. An ecosystem can be generalised down into a community of different biotic species living together, in conjunction with the abiotic factors that surround them.
A biome, also known as life zones, consists of all plants, animals, and other organisms, as well as the physical environment in a particular area. A biome is characterized by its’ plant life, climate, and location. Climate and physical features determine the boundaries of a biome. A biome is made up of many different ecosystems. Ecosystems tend to have the same plants and animals as neighboring biomes around the boundaries.
The aquatic ecosystems are home to some of the most diverse life forms on the planet. From plankton and plants to fish and even to large mammals, the aquatic ecosystem provides shelter to such a diverse range of life that few other ecosystems can ever compare to this large scope. In the aquatic ecosystem, there are many factors that allow for biotic life to flourish. Some of these factors include biodiversity, energy flow, and nutrient cycling. Not only do these factors allow for the prosperity of the aquatic ecosystem function, but also allow for the proper function of the other factors.
Did you know that aquatic ecosystems cover more than 70 percent of earth’s surface and that three quarters of the earth is covered with oceans, lakes, ponds, rivers, or streams? An aquatic ecosystem is a system composed of living organisms and non-living elements interacting in a watery environment; they also use each other and the water they reside in or near for nutrients and shelter. An ecosystem is an entity formed by the interactions between living organisms and the physical environment. Aquatic ecosystems can be divided into freshwater, estuarine, and marine systems. All of these ecosystems are vulnerable to climate change, pollution, and even over fishing, which can be a serious harm to biodiversity. The organisms that live in these ecosystems contribute to the healthiness of the ecosystems. The main three ecosystems I will focus on will be: freshwater, ocean, estuarine and wetlands.
The two ecosystem that are very different but similar in some aspects are the woodlands ecosystem and the desert ecosystem. The woodlands have a very wet and cold atmosphere in comparison to the desert which feels dry and sticky. These temperatures is what determines the distinct offsprings that live in each ecosystems. According to my observations, the woodlands are home to ducks, fishes, squirrels, and birds that enjoy a more cool place as their home. In comparison to the desert, it is inhabited by eagles, frogs, bugs, and snakes that like to be in a open space territory with constant exposure to heat. The woodlands make one feel as if you are in two different places at once that have different weathers. Automatically in the woodlands, one
Biomes are very large ecological areas on the earth’s surface, with plants and animals adapting to their environment. They play a crucial role in sustaining life on earth. Biomes are often determined by abiotic factors such as climate, relief, geology, soils, and vegetation. A biome is not an ecosystem. There are five major categories of biomes on earth, which include: desert, forest, aquatic, grassland, and tundra biomes.
The natural ecosystem provides both goods and services to us. The ecosystem goods are the things that people produced from soil, water and plants; Crops, Fibre, Timber, Livestock, Tourism, etc. are the example of ecosystem goods. And, at the same time people get a varieties of fundamental and life supporting services such as flood control, clean air and water, pollination of crops and other plants, natural hazard regulation, cultural, spiritual and aesthetic services which are called ES ( Kerr, G., 2010).
Every environment consists of different populations and ecosystems, two subjects that are studied heavily by some scientists. By definition, a population is a group of organisms of the same species living and interacting in a particular area (Pg. 451 Biology for a Changing World). On the other hand, an ecosystem is defined as the living and nonliving components of an environment, including the communities of organisms present and the physical and chemical environment with which they interact (Pg. 451 Biology for a Changing World).
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.
