Keystone species contribute to the “balance of nature” and biodiversity because if it is removed from a system, the ecosystem may change drastically and healthy ecosystems need a keystone to function. How do keystone species contribute to the “balance of nature” and biodiversity.
Why is keystone species important in an ecosystem?

What is the most important keystone species?
Bee. Bees have been declared the most important species on the planet, which comes as no surprise as they provide food and shelter to a humongous diversity of organisms.

What are keystone species?
There are three types of keystone species cited by many scientists: predators, ecosystem engineers, and mutualists. Predators help control the populations of prey species, which in turn affects the quantity of plants and animals further along the food web.
Does a keystone species have a large effect on an ecosystem?
