The environmental benefits of the bee are numerous. Their habitats are becoming increasingly fragmented, meaning patches of habitat are decreasing in size and becoming increasingly isolated and less connected. Keystone species include the lion, jaguar and grey wolf, which help balance vast ecosystems (e.g., Central and South American rainforests) by eating a diverse range of prey species.
