What is population ecology?

• The study of how only human populations affect the environment

• The examination of how populations interact with the environment and each other

• The statistical analysis of birth rates in human populations

• The study of genetic diversity within a single species

Which distribution pattern describes individuals that are spaced at equal distances from each other?

• Random

• Clumped

• Uniform

• Scattered

Which type of species has a broad ecological niche and can thrive in a wide range of environmental conditions?

• Specialist species

• Generalist species

• Endangered species

• Keystone species

What is a characteristic of specialist species?

• They are adaptable to many environments

• They have a high range of tolerance

• They are adapted to specific environmental conditions

• They are less likely to become extinct compared to generalist species

What is the relationship between immigration and population size?

• Immigration decreases population size

• Immigration helps the population size and birth rate increase

• Immigration has no effect on population size

• Immigration only affects genetic diversity but not population size

The graph shows a curve that starts near zero and rises steeply, forming a J-shaped pattern as x increases. Which type of growth curve is shown?

• Exponential

• Logistic

• J shaped

• Boom and bust

On the graph, the dotted horizontal line represents the:

• Survivorship

• Birth rate

• Carrying capacity

• Dominance hierarchy

The carrying capacity of a population is the highest level at which a population can be:

• Sustained

• Before it crashes

• Attained

• After it crashed
