Intro to Biodiversity and Ecosystem Services

Biodiversity, aka biological diversity, usually refers to

• the number of people on Earth

• the variety of species on Earth

• the number of animal species in a specific area

• the number of plant species in a specific area

species that are native to and found only within a limited area

• endemic

• exotic

• endangered

• extinct

Why is biodiversity important to ecosystems?

• It helps populations adapt to ecological changes.

• It increases at each level of the food chain.

Define genetic diversity

• disturbance in the environment conditions that cause genetic changes to occur in organisms

Define ecosystem diversity

• variety of ecosystems in a given area
