Population Logistic Growth Model

The population of an insect species shows an explosive increase in numbers during the rainy season followed by its disappearance at the end of the season. What does this show?

1.	S-shaped or sigmoid growth of this insect
2.	the food plants mature and die at the end of the rainy season
3.	Its population growth curve is of J-type
4.	The population of its predators increases enormously

Asymptote in a logistic growth curve is obtained when:

1. K = N

2. K > N

3. K < N

4. The value of 'r' approaches zero

The equation of Verhulst-Pearl logisitic growth model is

From this equation, K indicates:
1. Biotic potential
2. Carrying capacity
3. Population density
4. Intrinsic rate of natural increase

Which one of the following equations represent the Verhulst-Pearl Logistic Growth of population?

1.		2.
3.		4.
