19.4 - Predation

Question 1

Give the effect of predator prey relationship on population size

Answer 1

• predators eat their prey, thereby reducing the population of prey
• with fewer prey available the predators are in greater competition with each other for the prey that are left
• the predators population is reduced as some individuals are unable to obtain enough prey for their survival or to reproduce
• the prey population therefore increases
• with more prey now available as foos, the predators population is population in turn increases
