Question
When does exponential curve occurs?
- Great environmental resistance
- No environmental resistance
- No biotic potential
- None of these
Hint:
- Lack of competition for resources helps a species grow exponentially.
The correct answer is: No environmental resistance
- Exponential curve represents, a very idealistic model of population growth where there are no limiting factors, hence the right answer is non environmental resistance.
- Environmental resistance could include predators, competition for food and space, diseases.
- If these stresses are absent, only then a species can grow exponentially.
