What is an invasive species?
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
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
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
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
Kudzu has overgrown in many parts of Tennessee. What type of relationship does Kudzu have with the native ground plants?
Competition
Commensalism
Mutualsim
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.
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
Reproducing quickly
too many predators
What is one major concern about the spread of zebra mussels, an invasive species, in Tennessee waterways?
Zebra mussels only grow in shallow ponds, so they have minimal impact on larger rivers and lakes in Tennessee.
Zebra mussels are beneficial because they compete with larger fish species, helping smaller native fish to survive.
Zebra mussels improve water clarity, which leads to an increase in fish populations that benefit from clearer water.
Zebra mussels attach to boats and other surfaces, clogging water intake pipes and harming water quality, which negatively affects native fish and plant species.
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.
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
How do you feel about today's lesson?
Level 4: I understood 100% of what you taught!
Level 3: I understood about 75%, I want more practice though
Level 2: I only understood about 50% and I am struggling
Level 1: I am so lost and I did not understand a single piece of information
What makes a species invasive?
