What do we call the dotted line labeled "D" 
Public
Carrying Capacity

What is a "limiting factor"?
Something that limits the growth of a population in an ecosystem
100
Based on this graph, what will happen to the lynx and hare populations over the next 15 years?
The populations will continue to increase and decrease until they both reach a carrying capacity.
100
What is biodiversity?
A big variety of organisms/abiotic factors within an ecosystem
100
What is an invasive species?
Species that are not native to a particular ecosystem and can cause harm to the ecosystem, the economy, and human health
200
In an ecosystem, what is the carrying capacity?
the maximum number of individuals of a population that the environment can support is the...
200
Give at least 2 examples of a BIOTIC limiting factor.
Disease (bacteria), food availability, predators, etc.
200
When the hare population increases, what happens to the lynx population after?
Increases
200
What is the difference between biotic and abiotic factors?
Biotic factors are living organisms and Abiotic factors are non-living factors in an ecosystem.
200
What type of variable is Time?
INDEPENDENT
300
Identify a possible limiting factor that can cause the mouse population to reach its carrying capacity. 
Limiting Factors: predators, habitat, competition for resources
300
Give at least 2 examples of ABIOTIC limiting factors
drought, severe winter, natural disaster, lack of water, etc.
300
Why does the predator population lag behind the prey population? (i.e. predators increase AFTER the prey increase)
The prey is the food for the predator, so the increase in the prey means an increase in food for the predator. So, the predator population can grow.
300
How can biodiversity stabilize an ecosystem?
When there is a variety of plants and animals, there is a variety of resources available. If you remove one species, it does not have as big on an impact.

Where would more fluctuation occur?
a. Ocean
b. Lake
c. Pond
d. They would fluctuate the same
c. Pond

What is the carrying capacity? 
about 250

In a forest ecosystem, which of the following is the best example of a limiting factor for a rabbit population?
a. amount of grass/flowers available
b. the amount of sunlight
c. their fur type
d. rabbits have no limiting factors
a. amount of grass/flowers available
400
Why does the hare population decrease?
There are more predators at that time, so they are getting eaten more
400
What determines an ecosystem's carrying capacity?
Limiting factors: resources, stable animal/plant populations, variety of life
400
What is a possible explanation to a problem that has not yet been tested?
Hypothesis
500
Which of the following might cause the carrying capacity of this rabbit population to DECREASE?
a. increase in food for a few years
b. fewer predators
c. severe drought for a few years
d. more resources available in the ecosystem
c. severe drought for a few years

Based on this graph, what is the limiting factor for the hare population? 
the lynx population - predators!
500
What is the limiting factor for the lynx? 
The hare

What type of relationship do a deer and a wolf have?
Predator/Prey
500
Which group does not receive any change or test, serving as a benchmark to compare results?
Control group
