Define biodiversity and describe how biodiversity (the variety of life in a particular habitat or ecosystem) helps keep an ecosystem healthy.

Biodiversity is a variation of organisms (plants, animals and bacteria) in the world or a specific habitat. Biodiversity helps to keep an ecosystem healthy because there is more variation of food and different organisms can rely on each other for survival. Also it offers a larger more reliable food chain and if one species is suddenly wiped out, it won't impact the ecosystem as much as it would if the biodiversity was smaller.
