Populations and Population Growth Quiz

Which of the following defines exponential growth?

• When the population explodes in numbers, but then begins to slowly decline due to disease, lack of resources, etc.

• When a population grows really fast but then slows down due to environmental resistance.

• When a population grows at really fast rates. Doubling in number every generation.

• When a population stays steady, not growing or shrinking around the population's carrying capacity.

Which best describes logistic growth?

• Rapid growth of a population that reaches a peak then slowly starts to decline due to lack of resources.

• Population growth that is initially rapid, but begins to slow down due to the population approaching its carrying capacity (K).

• Population growth that is really fast. The population size doubles each generation

• Population growth that is slow, but steadily increases as resources become less and less abundant.

Certain organisms are considered endangered. What does this mean about their birth and death rates?

• Birth Rates > Death Rates. More organisms are being born than are dying.

• Birth rates < Death Rates. More organisms are dying than being born.

How would a high emigration rate affect a population's size?

• It would cause the population to grow

• It would cause the population to not change in size

• It would cause the population to fluctuate in size.

• It would cause the population to shrink

A population's carrying capacity is defined as...

• Maximum number of individuals the population can support before growth starts to rapidly expand

• Maximum number of individuals in the population the available resources can support before growth is halted

• Maximum number of individuals the population's resources can support before growth is stopped, and starts to rapidly decline

• Minimum number of individuals needed to get a population off the ground to begin growing exponentially
