Question

Which of the following statements is correct?

• A. Species diversity, in general, increases from poles to the equator
• B. Conventional taxonomic methods are equally suitable for higher plants and microorganisms
• C. Indias share of global species diversity is about 18%
• D. There are about 25000 species of plants in India

Answer 1

Answer: (A)

The correct option is A Species diversity, in general, increases from poles to the equator

In general, species diversity, in general, increases from poles to the equator. With very few exceptions, tropics (latitudinal range of 23.5° N to 23.5° S) harbor more species than temperate or polar areas. The reason is that tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable. Such constant environments promote niche specialization and lead to greater species diversity.

So, the correct answer is 'Species diversity, in general, increases from poles to the equator'.
