Interdependence within ecosystems

Ecosystems are made up of a community of organisms that interact with each other and their non-living surroundings. Organisms in an ecosystem are interdependent because they depend upon each other for the things they need to survive. All organisms depend upon producers to make the food that moves through food chains. Dead organisms and remains of living organisms provide food for other organisms. All living organisms depend upon decomposers that break down dead organisms and recycle useful substances for reuse.
