1. Answer: 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. Answer: 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. Answer: 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. Answer: 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.
