Unit 1 Lesson 3

The new island of Surtsey was formed near Iceland by a series of volcanic eruptions. Which of these processes occurred first on Surtsey?

• Plants grew on the island.

• Animals moved onto the island.

• A complex ecosystem developed.

• Lichens converted volcanic rock into soil.

In 1988 several large forest fires occurred in Yellowstone National Park. What process occurred after these fires?

• pioneer succession

• primary succession

• symbiotic succession

• secondary succession

Which of these best describes a climax community?

• a community of organisms that has reached a steady state through the process of succession

• a community of organisms that develops in a previously populated area after a disaster such as a fire

• a community that forms in an area that has not recently been inhabited, such as recently exposed rock

• a community in which new species that are better adapted to the conditions are replacing existing species

A coral reef is a low-resistance ecosystem. How would coral reefs likely be affected if global ocean temperatures increased slightly?

• They would grow.

• They would all die.

• They would decline.

• They would be unaffected.

What is the role of the pioneer species in Primary Succession?

• To kill any remaining organisms from before the disturbance

• To break down rock and rebuild soil

• To provide food for large animals

• To put fresh oxygen into the air
