Q. No.Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
| Assertion(A): | A population that fits the logistic growth model increases more rapidly at intermediate size rather than at relatively small and large sizes. |
| Reason (R): | The population growth rate decreases dramatically as the population size approaches the carrying capacity. |
In the light of the above statements, choose the most appropriate answer from the options given below :
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | Both (A) and (R) are false. |

The growth rate of a natural population equals zero:
| 1. | when N/K is exactly one |
| 2. | when N nears the carrying capacity of the habitat |
| 3. | when N/K equals zero |
| 4. | when mortality is greater than natality |

The sum of the environmental factors that tend to restrict the biotic potential of an organism is called environmental resistance. In the logistic growth equation dN/dt = rN[K-N/K], the environmental resistance is represented by:
| 1. | r | 2. | N |
| 3. | K | 4. | [K-N]/K |
