The definition of ecosystem is a system that is formed by a community of organisms interacting with their environment. Both living and nonliving things within a particular area make up the ecosystem.Know More
In nature, ecosystems can range in size from small ponds or a tree to larger areas like a desert. Everything in that area, from water and soil to animals and plants, make up an ecosystem. Even climate, light and air play important roles. If there is not enough light or the right nutrients in the soil to support plant life, the plants can die. This can cause a chain reaction that kills animals and destroys the ecosystem.
Natural disasters, changes in climate and human interactions can cause problems in an ecosystem. Because of this, healthy ecosystems are home to many different species. This helps protect the ecosystem from significant damage in the event something bad happens.
Ecosystems are formed of producers, consumers and decomposers. Producers, like green plants, make their own food. This allows animals to eat the plants to get their energy and other animals to get energy from eating other consumers. Decomposers are the plants and animals that help break down other plants and animals when they die. This helps to put nutrients into the soil that help future generations of plants to grow and start the cycle over.Learn more about Biology
Matter is recycled in an ecosystem through various cyclical processes, such as the oxygen cycle, carbon cycle, water cycle and nitrogen cycle. The oxygen cycle, for example, is driven by photosynthesis and enables the exchange of carbon dioxide and oxygen. In the water cycle, the processes of evaporation, sublimation and transpiration move water through an ecosystem.Full Answer >
The abiotic, or non-living, factors that affect an ecosystem include the local temperature, light intensity, geology and presence of pollutants. Additionally, factors such as the pH of the soil and the types of gases that are dissolved in a body of water are non-living factors to which living organisms must adapt. The weather conditions of an area are abiotic factors that influence the functioning of ecosystems.Full Answer >
Competition among animals plays a variety of roles in the ecosystem. Competition between animals of the same species may occur during mating seasons or over territory control; competition between different species may stem from limited resources in an area.Full Answer >
A natural ecosystem is an ecosystem that occurs as it would without the influence of human beings. The term “ecosystem” refers to all of the plants, animals, fungi, protozoans, bacteria and other organisms that live in the same area. All of these distinct species share highly interconnected lives and, in many ways, function as one unit.Full Answer >
