Question

This is a logistic growth curve for a population with r_max = 0.6 ind/ind/yr. The y-axis is population size (N) and the x-axis is time (years). Refer to the figure for questions 1-5. Do not include units for any answers that should be in numeric form. 1. What is the carrying capacity for this population? Your answer should be a numeral. 2. What is the per capita growth rate when the population is at its carrying capacity? Your answer should be a numeral. 3. What is the population growth rate when the population is at its carrying capacity? Your answer should be a numeral. 4. What is the population size when the population growth rate is the highest? Your answer should be a numeral. 5. At what point on the curve will the population have a per capita rate of increase of 0.6 ind/ind/year-- A, B or C?

Explanation / Answer

1.

The carrying capicity is the maximum population size a particular environment can support. In this case it is 1000.

2.

When the population is at carrying capacity the per capita growth rate is 0.

3.

When the population is at carrying capacity the population growth rate is 0.

4.

Population growth rate is highest at the point of inflection here given by point B. In the figure it is close to 500.

5.

The per capita growth rate is maximum near the starting point. Hence A will be the correct option.
