Question

Which of the formula is used for exponential population growth?

  1. fraction numerator d N over denominator d t end fraction equals r N
  2. fraction numerator d T over denominator d n end fraction equals r N
  3. fraction numerator D U over denominator D d end fraction equals r N
  4. fraction numerator D f over denominator D d end fraction equals r N

hintHint:

  • Population growth under no limitations.

The correct answer is: fraction numerator d N over denominator d t end fraction equals r N


    • dN/dt = rN is the formulae used to determine exponential population growth.
    • Exponential growth takes place when a population's growth rate stays constant, regardless of population size, making the population grow faster and faster as it gets larger.
    • It also has no limiting factors which can restrict the growth of the population.
