Sacred groves are especially useful in:
1. preventing soil erosion
2. year-round flow of water in rivers
3. conserving rare and threatened species
4. generating environmental awareness
Biodiversity of a geographical region represents:
1. | Species endemic to the region |
2. | Endangered species found in the region |

4. | Genetic diversity is present in the dominant species of the region. |
One of the most important functions of botanical gardens is that:
1. They allow ex-situ conservation of germplasm
2. They provide the natural habitat for wildlife
3. One can observe tropical plants there
4. They provide a beautiful area for recreation
