WHY does the predator population always lag behind the prey population?
Since the prey is the food source, it takes awhile for the predator to eat, reproduce, and increase in population.
They are usually bigger, so they take longer to increase in population.
They do not lag behind, it is just the way the graph is set up.
If they were to eat faster, it would not lag behind so much.
