The graph shows a model of growth of a bacterial population. Which of the following correctly describes the growth curve?

• demographic

• logistic

• limiting

• exponential

The maximum number of individuals of a particular species that a particular environment can support is its

• logistic growth

• carrying capacity

• age structure

• population

If a population grows larger than the carrying capacity of its environment, the

• death rate may increase

• birthrate may rise

• death rate must fall

• birthrate must fall

Which would be least likely to be affected by a density-dependent limiting factor?

• a small, scattered population

• a population with a high birthrate

• a large, dense population

• a population with a high immigration rate

Which of the following is a density-independent limiting factor?

• a struggle for food, water, space or sunlight

• predator/prey relationships

• flood damage from a hurricane

• parasitism and disease

• demogrpahy

• natural selection

• transition

Since the Industrial Revolution, human populations have

Demographic transition refers to a shift from

• high birthrates and death rates to low birthrates and death rates

• immigration and emigration

• population decrease to population increase

• logistic growth to exponential growth
