What is a keystone species, and why is it important to an ecosystem? And write it like a 7 grader

Answer 1

A keystone species is a type of animal or plant that plays a crucial role in its ecosystem. Without the keystone species, the ecosystem would change dramatically and might even fall apart. This is because the keystone species has a big impact on the other plants and animals in the ecosystem.

For example, if an ecosystem has a keystone species like a beaver, it would build dams that create new habitats for other animals. Without the beaver, the ecosystem might not have as much diversity and would not be as healthy.

Overall, keystone species are super important because they help keep the ecosystem in balance and functioning properly. If we lose a keystone species, it could have a big impact on the whole ecosystem.
