Question

What are food chains and food webs? Why are smaller food chains better? What is 10% flow?

Answer 1

The food chain is the chronological pathway or order that give information about the energy flow from producer to various consumers.

Food web is interconnected food chains.

Small food chains are better as the flow of energy is very small from one organism to another that it can support the animals after three or four trophic levels.

The 10% energy rule is given by Raymond Lindeman and according to the rule, only 10% of energy is transferred from one organism to another in a food chain.
