TN READY REVIEW 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 native species, ecosystems, or human activities.

Front

How can invasive species affect native species?

Back

Invasive species can outcompete native species for resources like food, water, and sunlight, leading to a decline in native populations.

Front

What is the role of predators in an ecosystem?

Back

Predators help control the population of prey species, maintaining balance in the ecosystem.

Front

What happens to coral reefs when harmful species like the Crown of Thorns Starfish increase in number?

Back

Harmful species can damage coral reefs, leading to a decrease in the size and health of the reef.

Front

What is the impact of overgrowth of invasive plants like Old World climbing vine on animal habitats?

Back

Overgrowth can reduce the availability of habitats for some animals, making it difficult for them to find shelter and food.

Front

What is the significance of beavers in an ecosystem?

Back

Beavers create dams that help maintain water levels, which supports various plant and animal life in the ecosystem.

Front

What does biodiversity mean?

Back

Biodiversity refers to the variety of different species in an ecosystem, which contributes to its resilience and health.

Front

How can introducing a non-native species increase biodiversity?

Back

In some cases, a non-native species may fill a niche that was previously unoccupied, potentially increasing the variety of life.

Front

What is the effect of removing a key species from an ecosystem?

Back

Removing a key species can disrupt the balance of the ecosystem, leading to negative consequences for other species.

Front

What is resource competition?

Back

Resource competition occurs when multiple species or individuals vie for the same limited resources, such as food, water, or space.
