Predation
is an interaction in which one organism, the predator, eats all or part of the body of another organism, the prey. Herbivory is a form of predation in which the prey organism is a plant. Predator and prey populations affect each other’s dynamics.
What is the relationship between predator and prey populations?
Predation and Population
A predator-prey relationship tends
to keep the populations of both species in balance
. This is shown by the graph in Figure below. As the prey population increases, there is more food for predators. So, after a slight lag, the predator population increases as well.

Why are predator/prey relationships important to ecosystems?
“
When prey are high, predators increase and reduce the number of prey by predation
. When predators are low, prey decrease and thus reduce the number of predators by starvation. These predator/prey relationships thereby promote stability in ecosystems and enable them to maintain large numbers of species,” says Allesina.
What are the four types of predators?
There are four commonly recognized types of predation:
(1) carnivory, (2) herbivory, (3) parasitism, and (4) mutualism
. Each type of predation can by categorized based on whether or not it results in the death of the prey.
What causes the predator population to decrease?
Predator and prey populations cycle through time, as predators decrease numbers of prey.
Lack of food resources in
turn decrease predator abundance, and the lack of predation pressure allows prey populations to rebound. … They have been particularly useful in understanding and predicting predator-prey population cycles.
