Invasive Species

Front

What is an invasive species?

Back

An invasive species is a non-native organism that spreads widely in a new environment and causes harm to the ecosystem, economy, or human health.

Front

What is a native species?

Back

A native species is an organism that naturally occurs in a specific region or ecosystem without human introduction.

Front

Why do invasive species thrive in new environments?

Back

Invasive species often thrive because they have few or no natural predators in the new environment, allowing their populations to grow rapidly.

Front

What is ballast water?

Back

Ballast water is water taken on by ships to maintain stability, which can unintentionally transport invasive species when discharged in new locations.

Front

What is the impact of invasive species on local ecosystems?

Back

Invasive species can disrupt local ecosystems by outcompeting native species for resources, altering habitats, and introducing diseases.

Front

How can invasive species affect food chains?

Back

Invasive species can alter food chains by preying on native species, leading to declines in native populations and affecting the entire ecosystem.

Front

What is one way invasive species are introduced to new areas?

Back

Invasive species can be introduced through human activities, such as shipping, trade, and gardening.

Front

What does it mean for a species to reproduce quickly?

Back

Reproducing quickly means that a species can produce a large number of offspring in a short period, which can lead to rapid population growth.

Front

What is an example of an invasive species?

Back

The zebra mussel is an example of an invasive species that has caused significant ecological and economic damage in North America.

Front

What role do predators play in controlling invasive species?

Back

Predators can help control invasive species populations by preying on them, but many invasive species have few or no predators in their new environments.
