Explain the term Emigration.
Show Hint
The opposite of emigration is immigration, which refers to individuals moving into a population.
Solution and Explanation
Emigration is one of the factors that influence population dynamics and affects the size of a population.
(i) It refers to the permanent movement of individuals out of a population, reducing the population size.
(ii) Emigration is an important component of population ecology, influencing genetic diversity, resource competition, and species distribution.
(iii) It is commonly observed in animals migrating to find food, escape harsh environmental conditions, or seek better breeding grounds.
Examples of Emigration:
Bird Migration: Birds leave colder regions in winter to migrate to warmer places.
Wildebeest Migration: Large herds of wildebeest migrate seasonally to find fresh grazing areas.
Human Emigration: People migrate from rural to urban areas for better job opportunities.
