Many possible answers

Why would a population grow like the population on the right instead of like the one on the left? Explain.
Limited resources and habitat have created a carrying capacity.

What is an ecological niche?
The role than an organism or population plays within an ecosystem.

Name an abiotic factor that would affect the dispersal of a plant population. Explain its effect.
Available carbon dioxide, available sunlight, available water, or wind are all possible answers.

What would you expect to happen to the population of this country moving forward? Explain.
Decrease because there are more old members of the population than members of the population who would have children.

Compare and contrast commensalism and mutualism.
They both involve the benefit of at least one organism while in commensalism one organism is unaffected while in mutualism both organisms benefit.

A young man is close to drowning and his sister is about to save him. There is a 25% chance of the sister drowning in the rescue and the average number of children for humans is 2. Is the sister saving her brother favored by natural selection? Support your answer.
The sister should save her brother because their relatedness (.5) is greater than the risk of dying (.25). This would result in rB > C.

Name a biotic factor that would affect the dispersal of a plant population. Explain its effect.
A competing plant species or herbivorous animal populations are both possible answers.
