Formula Components Representations A. dN/dt 1. Change in population size over time B. (b – d) 2. Intrinsic rate of natural increase C. Nt 3. Base of natural logarithms D. e 4. Population density after time t

Options

  1. AA - 1, B - 2, C - 3, D - 4
  2. BA - 1, B - 2, C - 4, D - 3
  3. CA - 2, B - 1, C - 4, D - 3
  4. DA - 3, B - 2, C - 1, D - 4

Correct answer

B. A - 1, B - 2, C - 4, D - 3

Step-by-step solution

The equation dN/dt = (b – d) × N describes the change in population size over time, (b – d) represents the intrinsic rate of natural increase, Nt is the population density after time t, and e is the base of natural logarithms.
