Invasive Species

coniferous forest (taiga)

desert

tundra

grassland

A native (naturally found) species which are added to an area

An organism that is new to an environment and has a negative effect on that environment.

A keystone species in an environment

none of the above

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

A type of biome

An invasive species

The home of a non-native organism

an organism’s role or place in an 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

Competition

Commensalism

Mutualsim

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.

the population of rabbits would increase

the population of eagles would increase

the population of eagles would decrease

there would be less sunlight

Reproducing quickly

too many predators

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.

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
