Invasive Species Pulse Check

What is an invasive species?

• A non-native species that causes harm to the environment, economy, or human health.

• A native species that benefits the environment, economy, or human health.

• A non-native species that has no impact on the environment, economy, or human health.

• A species that is only harmful to other species but not to the environment, economy, or human health.

How do invasive species impact ecosystems?

• Invasive species only impact certain ecosystems.

• Invasive species can have a positive impact on ecosystems.

• Invasive species can have a negative impact on ecosystems.

• Invasive species have no impact on ecosystems.

What are the effects of invasive species on native biodiversity?

• Invasive species have no effect on native biodiversity.

• Invasive species can outcompete native species, prey on them, disrupt ecosystems, and alter habitats.

• Invasive species can enhance native biodiversity.

• Invasive species only affect non-native species.

How can invasive species outcompete native species?

• Invasive species can outcompete native species by having a higher reproductive rate, lacking natural predators or diseases, and being more adaptable to the environment.

• Invasive species can outcompete native species by lacking natural predators or diseases, having a lower reproductive rate, and being less adaptable to the environment.

• Invasive species can outcompete native species by having a lower reproductive rate, lacking natural predators or diseases, and being less adaptable to the environment.

• Invasive species can outcompete native species by being less adaptable to the environment, having a lower reproductive rate, and being more susceptible to diseases.

What is the role of biodiversity in ecosystem stability?

• Biodiversity leads to increased vulnerability to environmental changes.

• Biodiversity has no impact on ecosystem stability.

• Biodiversity only affects certain species and not the entire ecosystem.

• Biodiversity provides resilience and resistance to environmental changes.

How does the loss of biodiversity affect ecosystem stability?

• The loss of biodiversity has no impact on ecosystem stability.

• The loss of biodiversity increases species interactions and enhances ecosystem resilience.

• The loss of biodiversity only affects certain species and does not impact overall ecosystem stability.

• The loss of biodiversity disrupts species interactions and reduces ecosystem resilience.

Explain the concept of biological control and its role in managing invasive species.

• Biological control is the process of genetically modifying invasive species to make them less harmful.

• Biological control is the use of natural enemies to manage invasive species.

• Biological control involves the relocation of invasive species to new habitats.

• Biological control is the use of chemicals to manage invasive species.

Why is it important to address the issue of invasive species for the conservation of biodiversity?

• Invasive species have no impact on native species and ecosystems.

• Invasive species can outcompete native species, disrupt ecosystems, and reduce biodiversity.

• Invasive species can enhance biodiversity by introducing new species.

• Addressing the issue of invasive species has no effect on conservation efforts.
