The decrease
No change
What will happen to the population of pikas if number of predators increase ?
Population increase
Population deacrease
Number of pikas not change
If the pikas population’s size grows so large more than the space and resources available in this area, this is
Overpopulation
Normal population
Lower population

Which of the following are examples of limiting factors
Water
Food
Carbon dioxide
Disease
Without limiting factors, populations would keep growing in perfict condetion
True
False

What does a limiting factor do?

Makes a population grow large
Stops a population from growing large
Limit amount of resources
In a forest , what is a limiting factor for a rabbit population?
Sunlight
Absence of predator
Availability of grass
what is happening to their population size at the one year mark.
The population size is increasing.
The population size is decreasing.
The population size is remaining the same.
The population size cannot be inferred from the graph
Which of the following explains what happened to the coyote population size when it reached its carrying capacity, and why?
The population size continued to increase because the ecosystem had not changed.
The population size stopped increasing because it had reached the largest number of coyotes that the ecosystem could support
The population size became zero because the ecosystem could no longer support the coyote population
The population size can no longer be inferred from the graph once carrying capacity is reached.
