Question

Population size is not determined by

• A. Birth rate
• B. Death rate
• C. Emigration
• D. Dimorphism
• E. Immigration

Answer 1

The correct option is D Dimorphism

Dimorphism is the differences in appearance between males and females of the same species, such as in colour, shape, size, and structure.

Population size is the actual number of individuals in a population. Population density is a measurement of population size per unit area which depends on the death and birth rate and emigration and immigration but it does not depend on the morphological difference in the organisms in the population.
