• A food chain is the representation of a single energy pathway from the producer to the consumer. The study of food chains in an area or habitat helps us to know about interactions among the different organisms and also their interdependence.

Thus we can say that if one element of the environments is damaged then the whole ecosystem is unbalanced.

Water Pollution

Deforestation
