Which habitat exhibits the greatest biodiversity?

• A habitat with 15 different species with about 300 individuals each
• A habitat with 10 different species with about 75 individuals each
• A habitat with 4 different species with about 150 individuals each
• A habitat with only one species with about 2000 individual

 Which biome is more likely to survive a change in the environment?

• High (rich) biodiversity
• Low (poor) biodiversity

True or False:  Biodiversity tends to decrease nearer the equator.

• true
• false

Tigers living in warm climates have thinner coats of fur than tigers living in cool climates. This is a result of

• general diversity 
• species diversity
• ecosystem diversity
• genetic diversity

The habitat of a moth species included trees with both light and dark colored bark.Therefore the moth species included both light and dark colored variants.Then the light-colored trees were wiped out by a disease, and within a few years nearly all the moths in this forest were dark colored. Which of the following choices BEST explains what happened?

• The light moths that survived all had dark offspring in order to adapt to the change.

• The dark moths were less visible to predators, so mostly light moths were eaten.

• The few light moths that survived did not mate, and therefore they had no offspring.

• The light moths changed their wing pigments to darker colors to avoid being eaten.

According to the theory of natural selection, why are some individuals more likely than others to survive and reproduce? 

• Some individuals pass on to their offspring new characteristics they have acquired during their lifetimes. 
• Some individuals are better adapted to exist in their environment than others are. 
• Some individuals do not pass on to their offspring new characteristics they have acquired during their lifetimes. 
• Some individuals tend to produce fewer offspring than others in the same environment. 

A Chinook Salmon fish in Alaska can produce between 2000-17,000 eggs in a single spawning. Which step of natural selection does this observation demonstrate?

• Overproduction
• Inherited variations
• Struggle to survive
• Differential Reproduction
