Multiple Choice

What is an invasive species?

Multiple Choice

What is a native organism?

• It is an organism that has always lived in that area

• It is an organism that is moved into a new location

• An organism that has to grow around water

• An organism that can thrive in any biome

Multiple Choice

What is the meaning of Niche?

• A type of biome

• An invasive species

• The home of a non-native organism

• an organism’s role or place in an ecosystem

Multiple Choice

Invasive species alter the ecosystem by reproducing in number _____. This leads to ______ food for the native species.

• Quickly, less

• Quickly, more

• Slowly, less

• Slowly, more

Multiple Choice

Why do the populations of invasive species grow so quickly? 

• Invasive Species are native to an area. 
• Invasive species are prey to many animals.
• Invasive species have no predators.
• Invasive species keep the ecosystems in equilibrium.

Multiple Choice

What do invasive species do to the biodiversity of their ecosystem?

• They increase biodiversity by adding to the population

• They decrease biodiversity because they deprive other organisms, which will cause them to die out

• They increase biodiversity by taking away niches of other organisms

• They decrease biodiversity by adding new niches to the ecosystem

Multiple Choice

Kudzu has overgrown in many parts of Tennessee. What type of relationship does Kudzu have with the native ground plants?

• Competition

• Commensalism

• Mutualsim

Multiple Choice

Which of the following best describes how an invasive species might disrupt an ecosystem and affect native populations?

• An invasive plant spreads rapidly in a forest, taking sunlight and soil nutrients from native plants.

• An invasive fish species is introduced into a river but remains isolated and doesn’t interact with other species, leaving the ecosystem unaffected.

• An invasive insect species arrives in a new area, but it only feeds on non-native plants that were introduced by humans, creating no competition with native species.

• An invasive bird species finds a role in the ecosystem by filling an empty niche, balancing with other species and increasing biodiversity without any negative impacts.

Multiple Choice

If a new, NON-NATIVE species that eats rabbits was introduced into this food chain, what would probably happen?

• the population of rabbits would increase

• the population of eagles would increase

• the population of eagles would decrease

• there would be less sunlight

Multiple Choice

Which of the following is a key characteristic of most invasive species?

• Ability to breathe in the air & in the water
• Large, sharp teeth
• Reproducing quickly

• too many predators

Multiple Choice

Which would be the best solution for controlling the spread of an invasive species in an ecosystem?

• Allowing the invasive species to spread naturally so it becomes part of the ecosystem over time.

• Providing additional food and shelter for native species to help them compete with the invasive species

• Removing all plants and animals from the ecosystem to prevent the invasive species from spreading further.

• Introducing a random predator from another ecosystem to reduce the invasive species' population, without researching its effects on native species.

Multiple Choice

Which of the following would be a solution to limit the amount of new invasive species that enters the US?

• By cleaning boats and equipment before moving them to a new body of water

• Releasing exotic pets and plants into the wild

• Purchasing and planting non-native species in their gardens without caution
