A greater a habitat's biodiversity, the greater will be that habitat's -

• sustainability over time with varying conditions.

• consumption of energy in the form of sunlight.

• temperature ranges across the seasons.

• distance to the nearest water source.

Why does biodiversity contribute to a habitat's sustainability?

• The more plants and animals in a habitat, the greater the biomass, which is how habitats store energy.

• The greater the number of species, the more competition there is for food between predators, which sustains their populations.

• Changing conditions that harm one species leave other species to survive and perhaps even thrive.

• Landforms change shape less frequently when there is a greater number of species using the land.

Which of the following most likely supports the most sustainable ecosystem?

• The habitat with the greater number of green plants

• The habitat with the greatest variety of living things

• The habitat with the warmest average temperature

• The habitat with the greatest number of consumers

How is the current decline in biodiversity different from the previous mass extinctions that Earth has experienced?

• It is happening much more slowly

• This time it is not really happening

• It is made worse by an asteroid hitting Earth

• This is being caused by humans

Which of the following is NOT a cause for the current decline in the biodiversity of our ecosystem?
