What does every food chain end with?

Detritivores and decomposers are the final part of food chains. Detritivores are organisms that eat nonliving plant and animal remains. For example, scavengers such as vultures eat dead animals.

Fungi and bacteria are essential to many basic ecosystem processes. Some types of fungi and bacteria can break down fallen wood and litter returning nutrients to the soil. Other types can fix nitrogen in the soil and help plants get nutrients from the soil.

Which animal can make its own food?
