Damaging Biodiversity

Habitat Destruction is the loss of natural habitat. This may include clearing forests or filling in wetlands

Multiple Choice

The loss of natural habitat is called...

• habitat development

• pollution

• habitat destruction

• biodiversity

Multiple Choice

The breaking of habitats into smaller pieces is called?

• habitat polarization

• habitat deformation

• habitat fragmentation

• habitat corruption

Multiple Choice

Why is habitat fragmentation hazardous to animals?

• Animals may not thrive in their new habitat

• If coral reefs die, so will many fish species that depend on them

• Habitat fragmentation does not pose a threat to animals.

• Habitat fragmentation causes loss of habitat for many organisms

Multiple Choice

Habitat fragmentation occurs when…

• An ecosystem is able to recover, or adjust easily to change

• The temperature of ocean water causes algae to leave coral reefs.

• A large area of habitat is broken up into smaller isolated areas

• Smaller fragments of a habitat join to make a large habitat

Multiple Choice

What are the greatest problems facing plants, animals, and people?

• habitat destruction

• illegal hunting

• introducing new species that can cause problems

• all of the above

Multiple Choice

Why do the populations of invasive species grow so quickly?

• Invasive Species are native to an area.

• Invasive species have no predators.

• Invasive species are prey to many animals.

• Invasive species keep the ecosystems in equilibrium.

Multiple Choice

What makes a species invasive?

• Not having papers

• Moving to a new ecosystem and taking resources from natives

• Plants that take up too much space
