Answer:
Density, dispersion, growth
Explanation
Population refers to the total number of all members of a species occupying a particular area or habitat at a given time. Populations are not static but change in size, structure and organization. Some of the characteristics of population are:
- Density which refers to the number of members of a species per unit area or volume.
- Dispersion refers to the spread and distribution of individuals of a species within a habitat.
- Growth is the rate of increase or decrease in the number of individuals in a population which is balanced by birth rate and death rate.
The issues that affect population include competition, predation, emigration, diseases and parasites.
