increase in biodiversity

decrease in biodiversity

c)

extinction of a population from the ecosystem

d)

removal of many populations of organisms

9.

What are three things that create biodiversity?

10.

The ocean ecosystem has a high sustainability because of

a)

strong, persistent currents

b)

predator/prey relationships

c)

green plants growing on the bottom

d)

the large variety of different organisms

11.

1. The ecosystem with the greatest sustainability will be the one that has the –

a)

greatest variety of different organisms

b)

highest annual precipitation

c)

lowest population of harmful insects

d)

fastest growing season of green plants

12.

Why does biodiversity contribute to a habitat’s sustainability?

a)

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

b)

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

c)

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

d)

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