Biodiversity Ecosystem Assessment

The ecosystem with the greatest biodiversity is the one that has the greatest:

• average annual rainfall.

• coverage of land area.

• variety of living things.

• elevation above sea level.

Which of the following would indicate the greatest problem with the health of an ecosystem?

• There has recently been a change in the ecosystem’s weather.

• The ecosystem includes only a few kinds of plants and animals.

• The average temperature in the ecosystem has increased slightly over many years.

• The population of top predators increases and decreases in a regular pattern.

Which of the following would be found in a very healthy ecosystem?

• A large number of green plants

• A warm, rainy climate year-round

• A great variety of living things

• A small population of top predators

Human activity can destroy coral reefs. Because so many organisms depend on the coral, this can have a negative effect on the ecosystem in shallow ocean waters. Which of the following solutions will most likely offer the best way for humans to repair the damage and improve the health of this ecosystem?

• Introduce non-native species into the shallow ocean that don’t depend on coral

• Design nets to catch the kinds of fish that use coral reefs as a food source

• Submerge large structures on which new coral reefs can form and grow

• Use submarines to gather data on the amount of coral reefs lost each year
