Question
Explain in detail the inter-relationship between the food chain and the food web.
Solution
Between producers, consumers, and decomposers, interaction is constant. There is a definite sequence in these interactions, which is called the food chain. Each chain consists of four, five or more links. An ecosystem consists of many food chains that are interconnected at various levels. Thus, a food web is formed. An organism may be the prey of many other organisms. For example, an insect feeds upon the leaves of various plants, but the same insect is the prey for different animals like frogs, wall lizards, birds, etc. Thus, many interconnected food chains form an intricate food web.
