Question

I don't think these are all right. I keep getting 3 wrong. Can someone tell me which are wrong?

• A population's dispersion pattern is related to

1. the likelihood of competition between individuals.
2. individuals' chance of finding a mate.
3. Both
4. neither

• A population has the greatest number of individuals

1. when numbers are near (or at) the carrying capacity.
2. when numbers are near half of the carrying capacity.
3. when numbers are at a minimum (near zero)
4. (none of the above - population sizes do not change.)

• A population's growth rate is likely to be highest

1. when numbers are near (or at) the carrying capacity.
2. when numbers are near half of the carrying capacity.
3. when numbers are at a minimum (near zero)
4. (none of the above - population growth rates do not change.)

• The size of a population

1. always increases to a maximum, then remains constant for ever.
2. may increase and decrease cyclically.
3. always increases to a maximum, then decreases to zero.
4. (none of the above)

• A life table is useful for

1. describing changes in population size over a range of time.
2. describing the range of individual reproductive rates in a population.
3. (both)
4. (neither)

• As song sparrow population density increases,

1. the average reproductive success of individual song sparrows tends to increase.
2. the average reproductive success of individual song sparrows tends to decrease.
3. the average reproductive success of individual song sparrows does not change.
4. the average reproductive success of individual song sparrows is unpredictable

Answer 1

1. A population dispersion pattern is related to the likelihood of competition between individuals.

2. A population has greatest number of individuals when the number are near at the carrying capacity.

3. A population's growth rate is likely to be highest , when numbers are near half of the carrying capacity.

4. The size of a population - always increase to a maximum then remains constant for ever.

5. Both .

6. The average reproductive sucess of individual song sparrow tends to decrease beacuse of mate competetion.
