Definition
An organism that captures and survives by feeding on other organisms is called as predator.
Introduction
The predator gains energy to sustain life and encourage its reproduction on the cost of an organism being eaten, the prey. Predators sit at the top of the food chain and consume its prey perched one trophic level below, which in return eats plants, the basis of the ecosystem (Hairston et al. 1960). Predator plays a very crucial role in framing the ecosystem structure and function. Predator-prey interactions change the community structure, arbitrate trophic cascades, and influence biodiversity and species invasions. Moreover, the prey population dynamics can be controlled by predators by affecting features such as survival, behavior, growth, size, structure, and distribution over an area. Besides animals, carnivorous/insectivore plants like the Venus fly trap and pitcher plant which feed on insects also show predation. These plant species grow in nitrogen-deficient soil....
