DESCRIPTION

Loss of Biodiversity 1.We share the environment with other organisms in a complex network. 2.Each species has a role or niche to play in its ecosystem. 3.If one species disappears from an ecosystem, the ecosystem changes. Keystone species are species that are so important to the functioning of an ecosystem that if they disappear, the ecosystem falls apart.
