Let's put it this way. Say you have a killerwhale and a penguin. Killerwhales are major predators to penguins. Now, say the killerwhale population increases. The penguins would be eaten more by the killerwhales, then causing a population decrease for the penguins. If the population decreases, they're won't be enough penguins, and they most likely will become extinct, as well as causing a population decrease for the killerwhales as well. Whereas, vis versa, they're were a killerwhale population decrease. The penguins would be less hunted, therefore, creating a population increase for the penguins.
what is the relationship between the size of the predator population and the size of he prey population
A predator-prey relationship tends to keep the populations of both species in balance. As the prey population increases, so, after a slight lag, the predator population increases as well. As the number of predators increases, more prey are captured.
predator hunts and eats prey.
a predator eats a prey.
The cat is the predator and the mouse is the prey.
predator kills and eats prey for its survival. When the predator population increases, the prey population decreases because of too many hunters. When the prey population decreases, the predator population decreases because of the lack of food. Then, the prey population increases because there aren't that many predators and the process repeats itself.
Predator-prey relationships can regulate population sizes by keeping prey populations from growing unchecked. Predators hunt and feed on prey, reducing their numbers. As prey populations decrease, predator numbers may also decline due to reduced food availability, which in turn can allow prey populations to recover. This cycle helps maintain a balance between predator and prey populations.
Because when a predator feeds on prey, the prey population goes down. When the prey population goes down, then so does the predator population. When the prey population recovers, then the predators soon after prey on the prey, and it repeats.
There always has to be more prey than predator. If there is less prey, it will get eaten by the predator and then the predator will starve. If there are not enough predators, the prey may overpopulize.
