Algae & Bass

Black Bear and Hawk

Black Bear & Perch

Perch and Algae

Increase in algae led to fewer black bears

The increased bass population led to more competition with hawks and reduced the available food

The black bear declined because the perch population increased

Increased in the hawk population led to few black bear

Limiting Factors

Biodiversity

Carrying Capacity

Habitat Destruction

Big animals such as elephants

Humans

Artificial Intelligence/Technology

Asteroids

water

land

air

Animals may not thrive in their new habitat

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

Habitat fragmentation causes loss of habitat for many organisms

Habitat fragmentation does not pose a threat to animals.

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

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

Smaller fragments of a habitat join to make a large habitat

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

The permanent removal of trees in the forest to make room for something else

Taking trees out of the forest and planting them somewhere

Taking trees out of the forest and planting them in another forest

Animals lose their homes.

Animals move to a new home and thrive.

Pollution

Microplastics create dead zones in the oceans

Wildlife such as dolphins, seals and seabirds often eat plastic, mistaking it for food

Plastics provide habitats for marine life

None of the above
