Accepted Answer

biogeography

Answer

ecology

Answer

entomology

Answer

chemistry

Question 12

The movement of organisms from one place to another is called ______________________.

Accepted Answer

dispersal

Answer

transition

Answer

spread

Answer

drift

Question 13

Which is NOT a factor in the theory of island biogeography?

Accepted Answer

Islands farther from the continent have more species due to increased speciation

Answer

dispersing species are more likely to find a large habitat

Answer

islands can also be isolated areas within a continent

Answer

larger habitats contain a larger range of environmental conditions

Question 14

Which of the following is true about island biodiversity?

Accepted Answer

Small islands have fewer resources and as a result may have fewer species

Answer

Small islands are more likely to have more immigrated species

Answer

Small islands have higher biodiversity than large islands

Answer

Small islands have more resources and as a result may have more species

Question 15

What prediction is correct about island biogeography?

Accepted Answer

Islands closer to mainland will be more diverse due to more successful dispersal.

Answer

Smaller islands have more resources, and will have more biodiversity

Answer

Larger islands have more space for resources, but will have less biodiversity due to competition

Answer

There is more diversity far away from the mainland because some species fly.

Question 16

What is the best way to reduce stress on the ecosystem's provisioning services?

Accepted Answer

Slow down population growth

Answer

Use electric cars

Answer

Limiting human access to national parks

Answer

Recycling

Accepted Answer

I and III

Answer

II only

Answer

III only

Answer

II and III

Accepted Answer

Community A has higher species evenness

Answer

Community A has the same biodiversity as community B

Answer

Both communities have the same species evenness

Answer

Community B has a higher species richness

Question 19
