Multiple Choice

Which type of survivorship curve is characterized by a constant death rate over the organism's life span?

• Type I

• Type II

• Type III

• Type IV

Multiple Choice

Based on the survivorship curve diagram, which organism is most likely to experience high mortality early in life?

• Human

• Mouse

• Oyster

• Dog

Multiple Choice

What is the main difference between Type I, Type II, and Type III survivorship curves?

• Type I has high mortality early in life, Type II has constant mortality, Type III has low mortality early in life.

• Type I has low mortality early in life, Type II has constant mortality, Type III has high mortality early in life.

• Type I has constant mortality, Type II has high mortality early in life, Type III has low mortality early in life.

• Type I has high mortality late in life, Type II has low mortality early in life, Type III has constant mortality.

Multiple Choice

The exponential growth model describes the increase in population size of a population that is not constrained by resources or space. The graph shows the elephant population in Kruger National Park, which appears to have been increasing exponentially from 1900 to 1965. From this graph, you can tell that

• none of the elephants died.

• a female elephant living around 1960 was more likely to have a baby than a

  female elephant living around 1920.

• the vegetation the elephants eat could support more than 5,000 elephants.

• the more elephants there are, the more tourists will visit the park.

• the elephants adapted to the new park conditions around 1955.

Multiple Choice

What is the predicted carrying capacity of the Daphnia culture?

• 60 Daphnia/50 mL

• 120 Daphnia/50 mL

• 135 Daphnia/50 mL

• 200 Daphnia/50 mL

Multiple Choice

If we had to put the r and the K selection on a

survivorship graph, which one, r or K, would go with

which type of survivorship, Type I or Type III?

• r-selection corresponds to Type III survivorship; K-selection corresponds to Type I survivorship.
• r-selection corresponds to Type I survivorship; K-selection corresponds to Type II survivorship.
• r-selection corresponds to Type II survivorship; K-selection corresponds to Type I survivorship.
• r-selection corresponds to Type III survivorship; K-selection corresponds to Type II survivorship.
