- All the life on earth along with biological variety in all its forms, from the genetic makeup of plants and animals to cultural diversity encompasses biodiversity. It is mainly measured by the components such as species richness and species evenness. Species richness is measure of number of species found in a community whereas species evenness measure the proportion of species on a given site. Species richness is usually measured by Alpha diversity, Beta diversity, Gama diversity
- Statement 1 is correct: Alpha diversity refers to the diversity within a particular area or ecosystem and is usually express in number of species. So it will represent the species diversity present within each forest or grassland patch of the slope.
- Statement 2 is correct: Beta diversity is a comparison of diversity between the ecosystems and different communities, usually measured as change in amount of species. It will scale the species diversity between any two patches and their communities.
- Gamma diversity is a measure of overall diversity for different ecosystem within a region and scale species diversity along the entire range of the mountain slope.

Consider the following scales of measuring species diversity: Alpha di...
Explanation:
Alpha Diversity:
- Alpha diversity refers to the diversity within a particular area or ecosystem.
- It is usually expressed in terms of the number of species.
- It provides information about the species richness and evenness within a specific habitat or community.
- The higher the number of species in a particular area, the higher the alpha diversity.
- Alpha diversity is a local measure of species diversity and focuses on the diversity within a specific location.
Beta Diversity:
- Beta diversity is a comparison of diversity between ecosystems and different communities.
- It measures the change in the amount of species between different habitats or communities.
- It provides information about the turnover or replacement of species between different locations.
- Beta diversity helps us understand how different habitats or communities are distinct from each other in terms of species composition.
- It is calculated by comparing the number of species shared between two or more habitats or communities.
- The higher the beta diversity, the greater the difference in species composition between habitats or communities.
Conclusion:
- From the above explanation, we can conclude that both statements are correct.
- Alpha diversity measures the diversity within a specific area or ecosystem, while beta diversity measures the difference in species composition between different habitats or communities.
- Therefore, option C, "Both 1 and 2," is the correct answer.
