Ecology and Biodiversity:

Biodiversity

   

Biodiversity

Biodiversity refers to the species diversity of the flora and fauna found in an ecosystem and can be used as an indicator of its health. Abundant biodiversity may represent health in one ecosystem, while in another the ecosystem may be optimal when occupied by only a few endemic species. Human activities, water quality and invasive species can alter and threaten the biodiversity of an ecosystem and thus the overall integrity of the ecosystem.
