According to the text, which of the following characteristics are associated with exponential population growth?

  • A: It occurs in an idealized, unlimited environment.
  • B: Population members have access to abundant food.
  • C: Population members reproduce at their physiological capacity.
  • D: The population size increases by a constant proportion at each instant in time.
  • E: It accurately reflects long-term natural population dynamics.

Explanation

Exponential population growth is described as occurring in 'idealized, unlimited environments' where 'members all have access to abundant food and can reproduce at their physiological capacity.' Under these conditions, the population 'increases in size by a constant proportion at each instant in time.' The text also clarifies that this 'unlimited growth does not occur for long in nature,' meaning it does not accurately reflect long-term natural population dynamics.
