Unit 7a: Biodiversity (Full Unit Review)

A community is

• Several different populations scattered across several states.

• Several different organisms in the same geographic area

• One type of organism in the same geographic area

• Several different populations in the same geographic area

A population is

• a group of similar species in different areas

• a group of the same species in the same geographic area.

• a group of several species in the same geographic area

• a group of several species along with their abiotic factors in a small area.

A very destructive typhoon would start:

• common succession

• primary succession

• secondary succession

• quaternary succession

Species that are critical to the functioning of an ecosystem are known as

• biodiversity

• keystone species

• main species

• native species

Biodiversity, aka biological diversity, usually refers to

• the same species in a general location

• the number of different species in a given area

• the number of animal species in a given area

• the number of plant species in a given area

High biodiversity is a sign of a healthy ecosystem.

• True

• False

This picture is a great example of (a)   biodiversity.

• high
• low

• moderate

Which do you think has a higher species diversity, a food chain or a food web?

• Food Chain

• Food Web

What are the three main types of Biodiversity? (Check all that apply)

• Endangered diversity

• Species diversity

• Genetic diversity

• High Risk diversity

• Ecosystem diversity

When would we see a climax community?

• A few days after a fire.

• After an ecosystem fully develops.

• Before pioneer species can be established.

• Only in primary succession
