How Do We Classify Biodiversity?

Question 0

Endimism

Answer 0

When an area becomes isolated over time then the species in that area can only breed there, making them unique. This occurs in places such as Hawaii and the Galapagos.

Question 1

Genetic erosion

Answer 1

When the gene poll of an endangered or animal diminishes.
Human activities cause this - people require animals such as bees and so if we made them go extinct then problems would arise.
Impacts of habitat change could cause species to go extinct such as deforestation.

Question 2

Species diversity

Answer 2

Different animals and plants different roles on the earth and so high biodiversity is important.
A large range of animals could provide food, medical research, breeding stocks and so on…
Taking away certain species would disrupt trophic levels and so the food chain.

Question 3

Ecosystem diversity

Answer 3

Protection over the area could control number of ecosystems. A protected area would have more.
Climate affects ecosystems - there will be less diverse range of ecosystems in areas with extreme climate.
