What is ‘predation’? Explain with the help of suitable examples why is it required in a community with rich biodiversity?

Predation is the interaction between organisms in which one organism known as the predator kills another organism which is known as prey. Predation is required in a community which is rich in biodiversity because:

(i) It helps in the transfer from one trophic level to the next trophic level.


(ii) It keeps the prey population under control and acts as a biocontrol.


(iii) It helps in maintaining the species diversity.


Examples of predation are a lion eating deer or a snake eating rats. This results in the transfer of energy from the prey to the predator. It keeps the prey organism population under control and it allows in the maintenance of species diversity by allowing organisms which are eaten by the prey to sustain life.
