Explanation:

• First question: Population density is defined as the number of individuals per unit area. Here, "five alligators per acre" is a measure of density.
• Second question: A survivorship curve is a graph that shows the likelihood of an individual being alive as a function of age. It does not focus on reproduction (first option) or population growth with carrying capacity (third option).
• Third question: Elephants have a K - selected strategy. They produce few offspring but invest a lot in their care, so each has a high probability of surviving to adulthood. Rodents (more r - selected, many offspring with less care) and oysters (produce many eggs with low survival of young) do not fit this description.
• Fourth question: Carrying capacity is the maximum number of individuals a habitat can support. Reproductive capacity is about an organism's ability to reproduce, and community size refers to the number of species or individuals in a community, not the maximum a habitat can support.

Answer:

• First question: density
• Second question: graph that plots an individual's likelihood of being alive as a function of age
• Third question: elephants
• Fourth question: carrying capacity
