Question
List any three important characteristics of a population and explain
✓
Answer
→ Population density : The number of organisms belong to same species in a given time and habitat is called population density.
→ Four basic processes, two of which (natality and immigration) contribute to an increase in population density and two (mortality and emigration) to a decrease.
→ Natality : Natality refers to the number of births during a given period in the population that are added to the initial density.
→ Mortality : Mortality is the number of deaths in the population during a given period.
→ Immigration : Immigration is the number of individuals of the same species that have come into the habitat from elsewhere during the time period under consideration.
→ Emigration : Emigration is the number of individuals of the population who left the habitat and gone elsewhere during the time period under consideration.
