Consider a population of 10 million cells with a per-capita birth rate of 0.002 (per unit time) and a per-capita death rate of 0.002 (per unit time). The expected number of cells after 10 generations is ______.
- A.1 million
- B.5 million
- C.10 million✓
- D.100 million
Correct Answer
(C) 10 million
Solution & Explanation
The intrinsic rate of natural increase r=(b-d)=0.002-0.002=0. The growth equation (dN)/(dt)=rN=0, so the population size does not change. Even after 10 generations it remains 10 million.
