Biodiversity

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 

• having a lot of the same organism.
• having a few of the same organism.
• having a lot of variety of different organisms.
• only having one of each organism. 

Biodiversity is the variety of ________ in a community.

• genes
• population
• species
• community

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 species that is likely to become extinct if protective measures are not taken immediately is known as

• threatened species

• endemic species

• keystone species

• endangered species

An exotic species is

• a species that is not native to a particular region

• a newly discovered species in a particular region

• a genetically modified species in a particular region

• a species that is native to a particular region

An endemic species is

• exotic and found everywhere

• exotic and found only in certain regions

• native and found only in a limited area

• native and found everywhere

a species that is not native to a particular region and has no natural predators and little competition

• consumer species

• producer species

• invasive species

• adapted species

Why are invasive species such a problem in their new ecosystem?

• a. The new ecosystem isn't adapted to their presence

• b. The new ecosystem is probably weaker than the native one
• c. They have mutations making them more adapted to the new ecosystem
• d. They cause mutations in the native species
