What is the role of predators in ecosystems?

What is the role of predators in ecosystems?

Predators help maintain the balance of ecosystems by controlling prey populations, which prevents overgrazing and promotes biodiversity.

Can you give an example of a predator and its impact on the ecosystem?

Sure! Wolves in Yellowstone National Park help control the elk population, which in turn allows vegetation to thrive and supports other wildlife.

What happens if a predator is removed from an ecosystem?

If a predator is removed, prey populations can explode, leading to overgrazing, habitat destruction, and a decline in biodiversity.

Are there any ecosystems where predators are not necessary?

Some ecosystems can function without predators, but they often rely on other forms of population control, like disease or competition.
