5. In one species of bird, there are three varieties of feather color. What is this an example of?
ecosystem diversity
species diversity
genetic diversity
color diversity

6. Which is one event that may lead to Primary succession?
clear-cutting
climate change
volcanic eruption
introduced species

7. On May 18, 1980, Mount St. Helens in Washington State experienced a huge volcanic eruption after a magnitude 5.1 earthquake. During the eruption, hot ash and pumice poured down the west, south, and east sides of the mountain, melting the snow and ice at the top of the volcano and producing volcanic mudflows. Which type of process first occurred in the ecosystem around Mount St. Helens after it erupted?
primary succession
secondary succession
a climax community
species extinction

8. What is the role of a pioneer species in primary succession?
to destroy parasites
to provide shade
to provide fruit
to produce the soil

9. According to the pie chart, which cause results in the most extinctions?
A pie chart titled Causes of Extinction is shown. Introduced species, 39 percent; Habitat loss, 36 percent; Hunting and poaching, 23 percent; Other, 2 percent.
other
introduced species
habitat loss
hunting and poaching

10. Why are lichens a good pioneer species after a volcanic eruption?
They are able to grow on moist soil.
They are able to grow on bare rock.
They are able to attract animals.
They are able to grow without water.
