What is an ecosystem?
- An ecosystem consists of animals, plants, and microorganisms living together.
- Each group of similar living things is known as a community, and their living area is called a habitat.
- For example, in a woodland habitat, there are communities of rabbits and foxes. These communities, along with all other living things in the area, form the ecosystem.
Examples of ecosystems and how they change
- An ecosystem is made up of a community of animals, plants, and microorganisms, along with their habitat.
- For instance, a pond ecosystem includes a pond habitat with aquatic plants, microorganisms in the mud, fish in the water, and a heron on the bank.
- Some ecosystems, such as coral reefs, rainforests, and woodlands, have numerous communities of living things. Others, like deserts and polar regions, have far fewer.
- Changes to one organism in an ecosystem can impact others. For example, if all the foxes in a habitat are eliminated, the rabbit population might increase rapidly. Similarly, if all the fish in a pond are caught, the heron would have to leave to find food elsewhere. Thus, all populations in an ecosystem are interdependent.
