Biology 3.2 Quizizz: Invasive Species

When taken to a new habitat, non-native plants often threaten native plants of the new habitat.  Why do they do this?

• Non-native plants are able to mutate rapidly
• Non-native  plants cause native animals to relocate
• Non-native plants are able to be used for medicine
• Non-native plants compete with native plants for resources

What effect will an invasive species have on the carrying capacity of the native organisms in an ecosystem?

• The carrying capacity will increase
• The carrying capacity for all organisms in the ecosystem will decrease

• The carrying capacity will only decrease for those in competition for same resource
• The carrying capacity for all animals will stay the same

Biodiversity refers to

• extinct species
• the variety of species on Earth
• nonrenewable resources
• the rate of species decline

Kudzu has overgrown many parts of southern Missouri and native ground plants have disappeared from the area. This is an example of:

• Parasitism between kudzu and the native plants
• A predator prey relationship between ground plants and kudzu
• Competition occurring between the native and invasive species
• Commesalism occurring between the kudzo and native plants

The field mouse population in Australia has grown so fast that they eat an average of  $4 billion of wheat every year. Their fast growth is caused by:

• A. The mice like to reproduce
• B. A lack of a native species to eat the field mouse
• C. Abundant food supply
• Both B and C

1. What makes a species invasive?

• Moving to a new ecosystem and taking resources from native organisms

• It's from outer space

• Species that can't adapt
• Plants that take up too much space

If a blue catfish is introduced and eats the large fish who eat the smaller fish, what will happen to the population of the smaller fish?

• Increase
• Decrease
• Stay the same
• No affect on smaller fish

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

• Ability to breathe in the air & in the water
• Type I Survivorship Curves

• Many are r-strategists that produce many offspring

• Most are top predators

What are characteristics of native species? (Select all that apply)

• A species that has a defined habitat and has lived in the same place

• A species who has come from another state or country

• A specie that has no "home" and travels for its whole life
• A species that has a defined niche

The lack of natural predators makes populations of invasive species unmanageable?

• True
• False
