In the Verhulst-Pearl logistic growth equation, dN/dt = rN((K - N)/K), what biological parameter does 'K' represent?

Answer and explanation

Correct answer: B. Carrying capacity of the environment for that specific population

- is population density at time ,
- is the intrinsic rate of natural increase,
- represents the carrying capacity, the maximum population size that a given environment can sustainably support with its available resources.
  1. Step 1: In nature, resources (food, space, nesting sites) are finite and become limiting as population density increases.
  2. Step 2: The Verhulst-Pearl logistic equation describes density-dependent population growth: .
  3. Step 3: In this equation:
Answer
Carrying capacity of the environment for that specific population
Why not the others: 'Intrinsic rate of natural increase...' is represented by the variable ; 'Total number of individuals migrating...' represents immigration (); 'Absolute extinction threshold...' is the minimum viable population size, not .
