Questions and Answers

At the carrying capacity, what is the relationship between the birth rate and the death rate?

  • Birth rate equals the death rate (correct)
  • Birth rate is lower than the death rate
  • Birth rate is higher than the death rate
  • Death rate is higher than the birth rate

    • What is a characteristic of exponential growth?

  • Population growth is slow and steady
  • Population growth is always linear
