Image
Predation is when an organism kills and eats another organism (prey) to gain energy necessary for reproduction. In the perspective of the prey, predation reduces fitness. Predation is therefore a type of antagonistic interaction, a biotic factor limiting species distribution [1][2]. However, predation is also important to promote biodiversity through adaptation[3]. Types of predation 1. Carnivory - a type of predation where one animal consumes another. Carnivory is obviously displayed by large animals. Examples of these are wolves hunting moose, eagles hunting monkeys, cats hunting mouse, etc. Another form of carnivory is group predation.
