The number of species in a given area is known as

• species richness

• phylogeny

• species evenness

• biodiversity

Which is the best description of species evenness?

• how evenly spread out a particular species is within an ecosystem

• the number of species within an ecosystem

• the number of organisms present within an ecosystem

• the relative dominance of each species within an ecosystem

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Which of the following is true about island biodiversity?

• Small islands are more likely to have more immigrated species

• Small islands have higher biodiversity than large islands

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

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

What prediction is correct about island biogeography?

• Smaller islands have more resources, and will have more biodiversity

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

• Islands closer to mainland will be more diverse due to more successful colonization

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

The theory of island biogeography suggests that species richness is affected by which of the following factors?

I. island distance from mainland

II. how the island is formed

III. island size

• II only

• III only

• I and III

• II and III

What term describes the variety of different organisms found in an ecosystem?

• population
• biodiversity
• ecosystem services

The LESS genetically diverse a population is, the better it can respond to environmental stressors

• True

• False
