Enables life to adapt to and survive dramatic environmental changes.

• functional diversity
• genetic diversity
• ecosystem diversity
• species diversity

The earth's variety of deserts, grasslands, forests, mountains, oceans, lakes, rivers and wetlands.

• ecosystem diversity
• functional diversity
• species diversity
• genetic diversity

The variety of processes such as matter cycling and energy flow taking place within ecosystems as species interact with one another in food chains and food webs.

• species diversity
• genetic diversity
• ecosystem diversity
• functional diversity

A change in the genetic characteristics of a population from one generation to another.

• evolution
• emigration
• species richness
• extinction

Occurs when some individuals of a population have genetically based traits that enhance their ability to survive and produce offspring with the same traits.

• evolution
• genetic drift
• arrogance
• natural selection

Genetic variety occurs through random changes in the structure of DNA that can be inherited by offspring. These sometimes beneficial changes are called

• insignificant
• defects
• mutations
• serendipity

You saw an attractive person while you were walking down the street and you ran smack into a pole, causing damage to your face. Will this cause an inheritable mutation? 

• Yes, I'd better be careful.
• No, that's silly.

What is biological fitness?

• the ability to run long distances (stamina)
• the ability to reproduce successfully
• The ability to lift lots of weight (strength)
• the quality of a males' pick-up lines

Raccoon: specialist or generalist?

• specialist
• generalist

A species which serves as an early warning sign that a community or ecosystem is being altered or degraded.

• a keystone species
• a native species
• an indicator species
• an alarm species
