What happens to a food web if a top predator is removed?

Back

Front

What is the relationship between predator and prey?

The predator-prey relationship is a biological interaction where one organism (the predator) hunts and eats another organism (the prey).

Energy flows from producers to consumers and then to higher-level consumers, with energy decreasing at each trophic level.
