Question

write a common feature between food chain and energy flow in nature

Answer 1

Common feature between food chain and energy flow is that both involve trophic levels of organisms and the direction of flow is same for both i.e. from sun to autotrophs and then to heterotrophs. ... There will not be any flow of energy across the food chain.

Answer 2

Food chain follows a single path whereas food web follows multiple paths. From the food chain, we get to know how organisms are connected with each other. Food chain and food web form an integral part of this ecosystem. Let us take a look at the food chain and a food web and the difference between them.
