Question

functions of a food chain

Answer 1

Consumers are organisms that receive energy by consuming other organisms. Consumers dominate most of a food chain.

They have important roles to play within an ecosystem such as balancing the food chain by keeping in a animal populations at a reasonable number. Without proper balance, an ecosystem can collapse.

The three roles demonstrated by all animals, plants, bacteria and other living organisms are those of producers, consumers and decomposers.

Producers include plants and algae. Consumers are further broken down into primary, secondary and tertiary consumers, as well as carnivores, herbivores and omnivores.
