What is an ecosystem?
Ecosystems are the interactions of the biotic components (living things such as people.
plants, animals and microorganisms) and abiotic components (non-living things such as
soil, water and air) in a geographic area and the natural cycles that sustain those
components. An ecosystem can be large, like the ocean, or small, like the holdfast of a
kelp plant
There are many different fields of science that focus on different aspects of ecosystems.
When scientists in multiple fields are able to share their data and perspectives, a larger
view of an ecosystem is produced.
