Q. No.In which of the following interactions both partners are adversely affected?
| 1. | Competition | 2. | Predation |
| 3. | Parasitism | 4. | Mutualism |
According to Darwin, organic evolution is due to:
| 1. | Interspecific competition. |
| 2. | Competition within closely related species. |
| 3. | Reduced feeding efficiency in one species due to the presence of interfering species. |
| 4. | Intraspecific competition. |
| List-I | List-II | ||
| A. | Migratory flamingoes and resident fish in South American lakes | I. | Interference competition |
| B. | Abingdon tortoise became extinct after introduction of goats in their habitat | II. | Competitive release |
| C. | Chathamalus expands its distributional range in the absence of Balanus | III. | Resource partitioning |
| D. | Five closely related species of Warblers feeding in different location on the same tree | IV. | Interspecific competition |
1. A-I,B-IV,C-III,D-II
2. A-IV,B-I,C-II,D-III
3. A-III,B-I,C-II,D-IV
4. A-II,B-IV,C-III,D-I
| Statement I: | When the fitness of one species is significantly lower in the presence of another species, the process is defined as competition. |
| Statement II: | When fungi remain in association with living plants or animals, they are called saprophytes. |
1. Both Statement I and Statement II are True
2. Both Statement I and Statement II are False
3. Statement I is True but Statement II is False
4. Statement I is False but Statement II is True
| Statement I: | Gause's 'Competitive Exclusion Principle' states that two closely related species competing for the same resources cannot co-exist indefinitely and competitively inferior one will be eliminated eventually. |
| Statement II: | In general, carnivores are more adversely affected by competition than herbivores. |
In the light of the above statements, choose the correct answer from the options given below:
1. Statement I is incorrect but Statement II is correct.
2. Both Statement I and Statement II are correct.
3. Both Statement I and Statement II are incorrect.
4. Statement I is correct but Statement II is incorrect.
Two different species cannot live for a long duration in the same niche or habitat. This is:
1. Allen's law
2. Gloger's rule
3. Competitive exclusion principle
4. Weismann's theory
| 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. |

Inspite of interspecific competition in nature, which mechanism the competing species might have evolved for their survival?
| 1. | Mutualism | 2. | Predation |
| 3. | Resource partitioning | 4. | Competitive release |
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 |
The principle of competitive exclusion was stated by?
1. C. Darwin
2. G. F. Gause
3. MacArthur
4. Verhulst and Pearl
