Predation

                                                   19. Predation

This is a picture of a dragon fly. Dragon flies are an example of the term predation because they eat smaller insects. Predation is a symbiotic relationship between two organisms where one acts as a predator and captures and feeds on the prey. This is a mechanism of population control. When predators are scarce the population of prey should be large and vice versa. When the number of predators decline they change their hunting patterns and then predators rise again. As predators rise preys decline which leads to food scarcity for predators.
