More predators kill more prey , which, along with food scarcity, decreases the population. When prey becomes more scarce, the predator population declines until prey is again more abundant. ... When the predators are removed, prey populations explode.
What factors affect predator/prey populations?
These factors include, but are not limited to, the amount of food available for the prey, the number of different prey spe- cies available for a predator, and how fast the predator and the prey species reproduce .
Why does predator population lag behind prey?
Why does the predator population lag behind the prey population? ... The oscillation occurs because as the predator population increases, it consumes more and more prey until the prey population begins to decline . The declining prey population no longer supports the large predator population.
