Q. No.Which of the following links ecology to population genetics and evolution?
| 1. | Organismic ecology | 2. | Population ecology |
| 3. | Ecosystem ecology | 4. | Biome ecology |
A feature of ‘r’ strategists would be:
| 1. | few offspring | 2. | little parental care |
| 3. | sigmoid growth curves | 4. | a longer generation time |
Number of species in a community is an indicator of its:
| 1. | spatial heterogeneity | 2. | ecosystem productivity |
| 3. | species diversity | 4. | species richness |
All the following are the reasons for the increase in the population of present-day India except:
1. An increasing birth rate
2. A rapidly declining death rate
3. Decreasing maternal mortality rate
4. Decreasing infant mortality rate
The maximum population size of the species that the environment can sustain indefinitely is called as:
| 1. | biotic potential | 2. | natality |
| 3. | environmental resistance | 4. | carrying capacity |
