LS2.5/2.6 Invasive Species and Ecosystem Changes

Front

What are invasive species?

Back

Invasive species are non-native organisms that spread rapidly in a new environment, often causing harm to native species and ecosystems.

Front

Why do invasive species grow quickly in new areas?

Back

Invasive species grow quickly because they often have no natural predators in the new area.

Front

What is an example of an invasive species that harms native fish and clogs pipes?

Back

Zebra Mussel.

Front

How do invasive species affect food availability for native species?

Back

Invasive species increase in number quickly, leading to less food for native species.

Front

What type of ecological succession occurs after a disturbance that leaves the soil intact?

Back

Secondary succession.

Front

What is Kudzu and why is it considered invasive?

Back

Kudzu is an invasive plant from Asia that grows rapidly, covering native plants and blocking sunlight.

Front

What is one method to control the growth of Kudzu?

Back

Spray herbicide on it in the spring.

Front

What is the impact of invasive species on biodiversity?

Back

Invasive species can reduce biodiversity by outcompeting native species for resources.

Front

What role do predators play in controlling invasive species populations?

Back

Predators help keep invasive species populations in check, but invasive species often lack these predators in new environments.

Front

What is the difference between native and invasive species?

Back

Native species are organisms that naturally occur in a specific area, while invasive species are introduced from other regions and disrupt local ecosystems.
