Questions Related to diversity of life

Rate of replacement of species along a gradient of habitats/communities is called 

  1. $\alpha$ - diversity

  2. $\beta$ - diversity

  3. $\gamma$ - diversity

  4. $\omega$ - diversity


Correct Option: B
Explanation:

The local species pool is known as alpha diversity. It is also the diversity present within the community. Beta diversity is the diversity present between the communities. The diversity present in the ranges of communities is known as Gamma diversity.

So, the correct answer is 'β - diversity'.

The term biodiversity is related to 

  1. All living plants

  2. All living animals

  3. All living plants and animals

  4. Living plants, animals and microbes found in their natural habitats


Correct Option: D
Explanation:
Biodiversity is the term popularised by the sociobiologist Edward Wilson to describe the combined diversity at all the levels of biological organization. It is related to all living plants, animals, and microbes found in their natural habitats. There are more than 20,000 species of ants, 3,00,000 species of beetles, 28,000 species of fishes and nearly 20,000 species of orchids. The biodiversity is measured at three levels; genetic diversity, species diversity and ecological diversity.
So, the correct answer is 'Living plants, animals and microbes found in their natural habitats'.
