Biodiversity, Endangered & Invasive Species

Biodiversity, aka biological diversity, usually refers to

• the same species in a general location

• the variety of life in the world or in a particular habitat or ecosystem

• the number of animal species in a given area

• the number of plant species in a given area

Why is biodiversity important?

• Because all species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well

• Because it’s better to have only one variation of each species.

• Because it better to only have a few species on Earth.

• Honestly, I have no idea what biodiversity is!
