Question
Which of the following is the reason for decreasing the population size?
- Emigration
- Environmental resistance
- Immigration
- Limitation of carrying capacity
Hint:
The world population, which in 1900 was around 2 billion, climbed to around 6 billion in 2000. We observed a similar growth trend in India as well. The population boom is caused by an imbalanced death rate and development rate.
The correct answer is: Emigration
Emigration is the reason for decreasing the population size.
Overall, the population grows or shrinks through two very basic components- natural change and migration.
