2. Temperate forests
3. Deserts
4. Hill slopes
The highest number of species in the world is represented by:
| 1. | Fungi | 2. | Mosses |
| 3. | Algae | 4. | Lichens |
Among animals, which of the following is the most species-rich taxonomic group?
1. Insects
2. Molluscs
3. Crustacean
4. Other animal groups
What is/are the correct explanation(s) for the species richness of the tropics?
1. Tropics had less evolutionary time for species diversification.
2. Tropics provide a relatively constant environment.
3. Tropics receive more solar energy which contributes to greater productivity.
4. Both 2. and 3. are correct.
1. 3
2. 7
3. 10
4. 12
| 1. | Algae | 2. | Angiosperms |
| 3. | Bryophytes | 4. | Ferns and allies |
| 1. | The number of lichens is much more than the number of algae |
| 2. | The number of mosses is much less than the number of ferns and allies |
| 3. | The number of angiosperms is equal to the number of gymnosperms |
| 4. | The number of fungi is much more than the number of algae, ferns and allies, mosses and lichens put together |
