1populations that show uniform dispersion typically show the following characteristics except:

a. equal distance away from each other

b. intraspecies competition

c. cooperation

d. territorial behavior

2. organisms choose to live in a clumped dispersion for all of these reasons except

a. with access to food

b. it is decreases intraspecies competition

c. it increases mating possibilities

d. it is increases protection

3. sea turtles, mosquitoes, and frogs all show a

a. type 3 survivorship curve

b. type 1 survivorship curve

c. it depends on the location and mother laying it

d. type 2 survivorship curve

4. if the (births + immigrants) value is less than the (deaths + emigrants) value

a. the population is stable

b. the population is decreasing

c. the population depends on how fast they are dying

d. the population is increasing

1. C

Explanation: Species that are inclined to clumping means they are more likely to cooperate in tasking such as gathering food. However, evenly distributed population means there is competition between individuals hence the need to their own space and territory from the other individual.

2. B

Explanation: While the clumped up populations may be inclined to cooperate in tasks such as food gathering, such distribution results to increases intraspecies competition especially during scarcity. This is because the individuals are close together – which is also advantageous during mating season.

3. A

Explanation: Type 3 survivorship curve is characterized by a high mortality rate early in the life of the species which gradually progresses to a low mortality rate for the individuals that survive the early stages of life. These species, therefore, bear a lot of offspring most of which will not make to adulthood.

4. B

Explanation: If the death rate of a population is higher than the birth+ immigration rate, then the population must be decreasing. This can be demonstrated by a growth curve of a population such as that of bacteria. The population starts decreasing due to increased competition for reduced resources after reaching carrying capacity  - depicted by the stationary phase.
