Question

If prey are density dependent and the prey population has increased beyond its carrying capacity (e.g., due to immigration), which of the following will happen, as predicted by the isoclines? a) The predator population will grow and the prey population will shrink. b) The predator population will shrink and the prey population will shrink. c) The predator population will grow and the prey population will grow. d) The predator population will shrink and the prey population will grow. e) The predator will outcompete the prey, causing the prey population to go extinct.

Explanation / Answer

Prey means the food for the hunger called the predator. As the predator increses the prey decreases and the decrease in the prey results in the lack of food to the predator and its number also gradually decreases. Thus the isocline will be in a wave form of the prey-predator relationship.

Thus increase in the prey population will automatically increases the predator population and it shrinks the increased prey.

Hence the correct option is a
