Answer 2

Answer:

All matter is conserved in an ecosystem, but energy flows through an ecosystem. This energy moves from one organism to the next in what is known as a food chain. All living things need nutrients to survive, and food chains show these feeding relationships. If food is not consumed by organism then that organism lack nutrition , it may leads to that organisms death .
