The meaning of Ecology is the connection that exists between living organisms and their environment. From the largest animal on Earth to the smallest, they all share our world with us. The ecosystem is connected by the flow of matter and energy and as organisms eat and dispose of matter it supplies them to sustain life. Across the planet various densities of uneven configurations accumulate minerals and nutrients.
For example “Energy necessary for all life processes reaches the earth in the form of sunlight. By photosynthesis green plants convert the light energy into chemical energy, and carbon dioxide and water are transformed into sugar and stored in the plant.” Para 3 Columbia Encyclopedia:
Ecology Retrieved from http://www.answers.com/topic/ecology-1#ixzz2kYJo0zPj

An animal that eats plants acquires some of the stored energy by consuming the plant; Herbivorous are then used for food by meat eaters and then they pass on the energy to them.

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.
The associations between plants and animals and thei...

... survive in this community depends on their surroundings and their habits, breeding and consumption, that determines an animal’s station within the community.
Organisms just like us are aware of their environment. Animals can communicate by making sounds and body movement and leaving their scent. Plants can communicate through chemicals and color. Some plants use brighter colors to attract insects or other animals
Natural ecosystems function within the limits of their resources and are self sustaining. Over long period of times organisms can change their form and function this may cause them to no longer bear a resemblance to their original form.

Items that Are Part of Ecology Essay

- When asked to consider the term ecology I have to look at what that word is defined as being. The dictionary defines it as, “The branch of biology that deals with the relations of organisms to one another and to their physical surroundings” (online dictionary, 2013). This is a very short definition for something that is comprised of so much once you start thinking about how many things affect an organisms physical surroundings. For this, I will be focusing on energy and chemical cycles, community structure, biodiversity and succession, and how all of these items are a part of ecology....   [tags: energy & chemical cycles, community structures]

Deep Ecology Essay

- Deep Ecology/Ecosophy The ideas behind deep ecology have major implications today. They allow people to think more profoundly about the environment and possibly come to a better understanding of their own meaning. People are intensely concerned about the world’s technological adolescence, massive consumerism, and overpopulation. A man named Arne Naess, former head of the philosophy department at the University of Oslo founded an idea that can direct people’s anxiety away from their "shallow" notion of the problem to one that is much "deeper." "Deep ecology goes beyond the limited piecemeal shallow approach to environmental problems and att...   [tags: essays research papers]

Review of Wolves and the Ecology of Fear: Can Predation Risk Structure Ecosystems?

- In this article, authors William Ripple and Robert Beschta focus on the issue of predation and the way it affects biodiversity and otherwise alters ecosystems. While many other studies have stressed the lethal effects of predation by carnivores, the authors of this study have chosen to focus on how nonlethal outcomes of predation affect the structure and function of ecosystems. The authors give two main objectives to their study: first to provide a short synthesis of the potential ecosystem responses to predation risk in a three-level trophic cascade involving large carnivores, hoofed animals, and vegetation; and secondly to present research that centers on wolves, elk, and woody browse spec...   [tags: Ecology]

The Role of Competition and Predation in Ecology Essay

- Competition and predation are two key factors that affect the stability of an ecosystem, such as a lake. There are three theories on the affects of competition. Competition may lead to competitive exclusion, stable coexistence, or niche differentiation. It has been shown that in marine environments, species are strong competitors for both light and nutrients and thus competition leads only to competitive exclusion (Passarge et al. 2006). The competitive exclusion principle states that if two species compete for the same resource in the same location, then one of those species will go extinct because one species will be the better competitor (Jenson 2010)....   [tags: ecology]

Essay on Maryland's Ecology and Environment

- Maryland is the 42nd largest state, making it one of the smaller states in America. It is located in the South Atlantic region on the United States eastern seaboard. Prince George's is one of twenty four counties in Maryland. It is also the geographic center of the state. Maryland has a varied climate. The state is home to a variety of different ecosystems. This is also true of Maryland’s environment, which has the Atlantic Ocean on the coast, mountains, and forest land. My paper will focus on Prince George’s county and the state of Maryland....   [tags: Ecology ]

Essay about Indigenous Knowledge and Ecology

- The mistake of culture as timeless, knowledge as data Take a walk down Bourke’s main street and about midway, on the northern side, you will see a panoramic mural spanning the roofline of a simple brick building. It is a kind of timeline. At one end there is a panel devoted to Aboriginal life and Dreaming before colonisation, while the rest of the panels show a sequence of white exploration, pioneer settlement, a changing pastoral industry, reminders of historic floods, and a modern outback town....   [tags: Ecology]

The Impact of Sea Otters on Marine Ecology Essays

- Sea otters (Enhydra lutris) are marine mammals capable of spending their entire lives in water. Being carnivorous in nature, they feed on sea urchins, crabs, fishes, mussels and clams. They are referred to as keystone species due to their profound impact on marine ecology. The interaction between sea otters, sea urchins and kelp forests has been studied as a model of the impact of predator-prey interaction on community ecology. Sea otters are keystone predators, whose presence has a far-reaching influence on the marine food web by affecting the population of sea urchins in particular, and kelp forests & other marine organisms in general....   [tags: Ecology ]

Essay on Carbon Sequestration in Forest Ecosystems

- Carbon Sequestration in Forest Ecosystems Amid growing concerns about increasing concentrations of greenhouse gases in the atmosphere, mitigation techniques that reduce levels of greenhouse gases are receiving attention as a possible remedy for climate change. Forest ecosystems play an important role in the global carbon cycle, but there are still questions about how significant of a role they play and how manipulating management plans affects a forested area’s carbon sequestration potential. Various factors such as land-use history, age of a forest stand, and potential feedback processes must all be taken into account when determining if forests are a feasible method of climate change miti...   [tags: Ecosystems]

Bioerosion and Reef Ecology Essay example

- Bioerosion and Reef Ecology The breakdown of calcareous substrates among coral reefs, or bioerosion, is a facet of reef ecology too often forgotten. The process plays a much more important role than it is usually credited with. Bioeroding species, consisting of many different types of organisms that act on the environment in a seemingly endless variety of ways, interact with the ecosystem and with each other as part of the reef growth and degradation cycle. The degradation portion of this cycle, the part that is most often overlooked, is essential for the development of reefs as the diverse and beautiful habitats that we know them as....   [tags: Bioeroding Ecosystem Ecology Essays]
