## Populations

1.
A population will always grow exponentially
1. if it is limited only by density-dependent factors.
2. if there are no limiting factors.
3. if it is a population with an equilibrium life history.
4. None of the listed responses is correct.
2.
No population can grow indefinitely. The ultimate size of any population is limited by
1. the carrying capacity of its environment.
2. its death rate.
3. its birth rate.
4. its r value.
3.
Which of these factors increases the size of a population?
1. birthrate
2. emigration
3. death rate
4. carrying capacity
4.
The larger a population gets, the faster it grows is
1. sample counts.
2. exponential growth.
3. limiting factor.
4. carrying capacity.
5.
To calculate the human population density of your community, you would need to know the number of people living there and
1. the size of the area in which they live.
2. the birth rate of the population.
3. the dispersion pattern of the population.
4. whether population growth is logistic or exponential.
6.
Which factor would most likely be an example of a density-independent factor that limits population growth?
1. disease
2. food availability
3. daily temperature extremes
4. parasites
7.
What happens when a species has no natural predators?
1. The species dies.
2. The species moves.
3. The species' population grows.
4. The species' population declines.
8.
Which scenario best illustrates the concept of carrying capacity?
1. The exponential growth of a fruit fly population continues to increase and will eventually double in ten days.
2. The exponential growth of ants increases dramatically when its competitor species is forced to move due to habitat loss.
3. The logistic growth of a giraffe population continues to decline due to the increase in number of predators.
4. The logistic growth of a bunny population has stabilized because the population has reached the largest numbers that the area can support.
9.
With concern to the energy pyramid, which of the following statements best characterizes the relationship between plants and animals?
1. Plant production levels are unrelated to animal populations.
2. Plant production levels are inversely proportional to animal population size.
3. Greater plant production allows for a larger number of animal species.
4. Greater plant production allows for larger animal populations.
10.
What are the 3 stages of a population?
