Answer the following question in two or three sentences.
8. What is a predator-prey relationship? How does this relationship affect population size?
This relationship a ects population size in a cyclical manner. When the prey population
is high, the predator population also tends to increase due to the abundance of food. As
the predator population grows, it puts more pressure on the prey population, causing it
to decrease. Subsequently, with fewer prey available, the predator population declines.
