In a population of spiders there are three different sizes: small, medium, and large.
---The large spiders are easily seen by predators.
---Small spiders have a difficult time finding food.
What will most likely happen to this population of spiders after many generations?

Back

Medium spiders will be the most plentiful

Front

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. What happened?

Back

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

How is secondary succession different from primary succession?

Back

Secondary succession occurs after a disturbance in an area in which the soil has remained intact.

How did the environment change between time 1 and time 2? How did the population change?

Back

The environment became brown. With each generation, more brown foxes survived long enough to pass on the gene for brown fur to their offspring.

Importance of biodiversity to an ecosystem?
