Question

A decline in population size will be in simulation, when

• A. Natality < Mortality
• B. Mortallity < Natality
• C. Immigration < Emigration
• D. Emigration < Immigration

Answer 1

The correct option is A Natality < Mortality

Natality in population ecology is the scientific term for birth rate. Along with the mortality rate, natality rate is used to calculate the dynamics of a population. They are the key factors in determining whether a population is increasing, decreasing or staying the same in size. When mortality is greater than natality, this indicates a decline in population size and vice versa.

So, the correct answer is 'A'.
