Q. No.Carnivorous animals - lions and leopards, occupy the same niche but lions predate mostly larger animals and leopards take smaller ones. This mechanism of competition is referred to as:
| 1. | Character displacement | 2. | Altruism |
| 3. | Resource partitioning | 4. | Competitive exclusion |

Two butterfly species are competing for the same nectar of a flower in a garden. To survive and coexist together, they may avoid competition in the same garden by:
1. feeding at the same time.
2. choosing different foraging patterns.
3. increasing time spent on attacking each other.
4. predating on each other.

According to Darwin, organic evolution is due to:

| 2. | Competition within closely related species. |
| 3. | Reduced feeding efficiency in one species due to the presence of interfering species. |
| 4. | Intraspecific competition. |

Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R).
In the light of the above statements, choose the correct answer from the options given below:
| Assertion (A): | Connell's elegant field experiment showed that on the rocky sea, the larger and competitively superior barnacles dominate the intertidal area and exclude the smaller barnacles from that area. |
| Reason (R): | Generally, herbivores and plants appear to be more adversely affected by competition than carnivores. |
| 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. | (A) is False but (R) is True. |

The following graph depicts changes in two populations (A and B) of herbivores in a grassy field. A possible reason for these changes is that:
| 1. | both plant populations in this habitat decreased |
| 2. | population-B competed more successfully for food than population-A |
| 3. | population-A produced more offspring than population-B |
| 4. | population-A consumed the members of population-B |

An ecologist studying several forest-dwelling, insect-eating bird species does not find any evidence of interspecific competition. The most likely explanation is
| 1. | lack of a keystone species |
| 2. | low species richness |
| 3. | pronounced intraspecific competition |
| 4. | resource partitioning |
