ASU Bio 182 Exam 3
1. How would you estimate the number of mark and recapture
whales in a population?
2. What is a population? a group of individuals of the
same species living in the
same area at the same time
3. True or False? Sampling quadrats would false
be the better method for estimating the
number of whales in a population.
4. True or False? Mark and recapture would true
be the better method for estimating the
number of saguaros in a population.
5. The human population has grown exponentially
6. Explain what exponentially growing Compounded, like compound-
means? ed interest
7. The growth of a population depends on the birth rate minus the death
rate.
8. A population stops growing when it reaches its carrying capacity.
9. True or False? The carrying capacity of true, populations cant grow if
a population depends on the resources theirs no resources to support
available in the environment. them.
