What is an invasive species?

Back

An invasive species is a non-native organism that spreads rapidly in a new environment, often causing harm to native species and ecosystems.

Front

Why do invasive species grow quickly in new environments?

Back

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

Front

What is a niche in an ecosystem?

Back

A niche is the specific role or function of an organism within its environment, including its food sources and interactions with other organisms.

Front

What are some characteristics of invasive species?

Back

Invasive species are often fast-growing, reproduce quickly, and can thrive in a variety of conditions, outcompeting native species.

Front

What does it mean for a species to be non-native?

Back

A non-native species is one that is introduced to an area where it does not naturally occur.

Front

What is the impact of invasive species on ecosystems?

Back

Invasive species can disrupt local ecosystems by outcompeting native species for resources, leading to declines or extinctions of native populations.

Front

What is an example of an invasive species?

Back

Examples of invasive species include the Asian carp, zebra mussels, and the Burmese python.

Front

How can invasive species be controlled?

Back

Invasive species can be controlled through methods such as physical removal, chemical treatments, and biological control using natural predators.
