Front

How can invasive species affect agriculture?

Back

Front

What is one way to control invasive species?

Back

One way to control invasive species is through biological control, which involves introducing natural predators or diseases.

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 non-native and can disrupt the local ecosystem.
