Geography

Ecosystems exist literally all over the world. Deserts, oceans, plains and mountains are all considered ecosystems, as they each host species and organisms that work together to make up and sustain their environment.

Features

There are major parts that comprise every ecosystem. These features include atmosphere, soil, heat and light from the sun, water and living organisms.

Identification

Living organisms within ecosystems are typically divided into three categories: consumers, producers and decomposers. Consumers include herbivores, carnivores and omnivores. Producers are plants that make their own food and provide nourishment for some consumers. Decomposers may consist of plants or animals, and play a vital role in the breaking down of dead organisms into organic material.

Significance

Healthy ecosystems are ones that remain self-sufficient and survive despite the environmental impact of humans. Many environmental organizations work to preserve ecosystems and habitats, as ecosystems play a key role in Earth's natural processes.

History

The term ecosystem was first used by British scientist Arthur Tansley. His term described an interrelated system of organisms, both living and non-living, that comprise a natural environment.
