SY24 Invasive Species Flashcard

Front

What are invasive species?

Back

Invasive species are non-native organisms that spread widely in a new environment and can cause harm to native species, ecosystems, and human activities.

Front

How do invasive species spread?

Back

Invasive species can spread through various means such as accidental introduction, intentional release, natural dispersal, and human activities.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species and their interactions.

Front

How do invasive species affect biodiversity?

Back

Invasive species can decrease biodiversity by outcompeting native species for resources, disrupting food webs, and altering habitats.

Front

What is the role of early detection in managing invasive species?

Back

Early detection allows for timely intervention, making control measures less costly and more likely to be successful.

Front

What is a non-native species?

Back

A non-native species is an organism that is introduced to a new environment where it does not naturally occur.

Front

What is the impact of invasive species on ecosystems?

Back

Invasive species can alter ecosystems by changing species composition, disrupting food chains, and affecting nutrient cycling.

Front

What are some methods to manage invasive species?

Back

Management methods include early detection and rapid response, control and eradication efforts, and prevention of further spread.

Front

What is the significance of the Asian Carp as an invasive species?

Back

Asian Carp spread rapidly in North American waters, outcompeting native fish and disrupting aquatic ecosystems.

Front

How do invasive species like the Zebra Mussel affect freshwater ecosystems?

Back

Zebra Mussels can decrease biodiversity by outcompeting native species and altering the physical environment of freshwater ecosystems.
