Question
What is 'predation'? Explain with the help of suitable examples why is it required in a community with rich biodiversity.
✓

Answer

Predation is an interaction where one organism (predator) kills and eats the other weaker organism called prey. Predation is a natural way of transferring the energy fixed by plants, to higher trophic levels.
Examples: snake eating a frog, tiger killing and eating a deer. Predators keep prey population under control which otherwise could achieve very high population densities and cause instability in ecosystem. They also help in maintaining a species diversity in a community by reducing the intensity of competition among competing prey species.
