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

Succession that occurs in areas that previously didn't support life, such as on rocks or ice

• tangential succession

• primary succession

• secondary succession

• quaternary succession

A common type of succession that occurs where an event such as a forest fire has occurred

• common succession

• primary succession

• secondary succession

• Quaternary succession

Which habitat exhibits the greatest biodiversity? Species Richness? Species Evenness?

• A habitat with 15 different species with about 300 individuals each

• A habitat with 10 different species with about 75 individuals each

• A habitat with 4 different species with about 150 individuals each

• A habitat with only one species with about 2000 individual

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!
