APES Unit 2: Biodiversity Quick Review

Which of the following ecological levels of organization are arranged from largest to smallest?

• ecosystem, population, community

• biosphere, ecosystem, community

• community, population, ecosystem

• biosphere, population, ecosystem

Compared with a population with low genetic diversity, a genetically diverse population is more likely to include individuals that

• are distributed over a large area.

• vary greatly by age.

• vary greatly by appearance and behavior.

• each carry a large number of genes.
