| Assertion (A): | Population ecology links ecology to population genetics and evolution. |
| Reason (R): | It is at the population level that natural selection operates to evolve the desired traits. |
| 1. | Both (A) and (R) are True and (R) explains (A). |
| 2. | Both (A) and (R) are True but (R) does not explain (A). |

In an area, there are 200 carrot grass plants but only a single huge banyan tree with a large canopy.
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
| I. | The ecological role of the banyan tree in this community is negligible when compared to that of carrot grass. |
| II. | In this community, the percent cover or biomass is a more meaningful measure of the population size. |
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect

| Assertion (A): | The number of fish caught per trap is not a good measure of its total population density in the lake. |
| Reason (R): | For ecological investigations, it is obligatory to count every individual in a population to estimate population density. |
| 1. | Both (A) and (R) are True but (R) does not explain (A). |
| 2. | Both (A) and (R) are False. |
