Analyze if the following pairs of statements are correct.
Choose: A, if both statements are correct; B, if only the first statement is correct; C, if only the second statement is correct; or D, if both statements are incorrect.
2a. Population density refers to the number of individuals within a designated area.
2b. Richness pertains to the number of species present in a specific location.
1. On the savannah of African exist two animals, the African Wild Dogs (Lycaon pictus) and the Spotted Hyenas (Crocuta crocuta). Both of these animals occupy a very similar niche in their community – a social carnivore, which hunts in packs. However, when their niche does completely overlap the Hyena will win the fight. Use this information to answer the following questions.
a) If these two animals were to occupy the same habitat, knowing what you know about these populations, what do you think the outcome of these two populations would be?
b) The African Wild Dog hunts at twilight, while the Spotted Hyenas hunt at night. This separation of niches allows for what ecological process to happen? Why is it important that this process happens?
c) The population of African Wild Dogs is much smaller, and very isolated from one another. If you were trying to prevent this animal from going extinct – what would you focus your resources on conservation wise? (There are a number of answers for…

A drought occured reducing the size of a large lake that was home to a species of aquatic snail in a very short period of time. The remaining population saw a drastic reduction in the gene pool and faced new selective pressures due to the lack water. Those snails that were drought tolerant sirvived and became a new species.

How do you expect the genetic diversity of the island turtles to compare to genetic diversity of the mainland turtle population they originated from? Group of answer choices A. Genetic diversity should be similar, since they are the same species. B. Genetic diversity should be higher for the island turtles, because the new environment will produce new alleles. C.
