biodiversity on earth.
(b) According to Robert May estimates, the
global species diversity is 7 million.
(c) Biodiversity is the greatest in tropics.
(d) All of these.

Answer 1

Answer:

d) All of these is the right Answer !!

Answer 2

Option (d) All of these is the correct statement.

Explanation:

• Amazonian rain forest has greatest biodiversity on earth since it is covered with huge forest vegetation, flora and fauna.

1. Being in the tropical zone that is not explored much and at the same time experiences stable, predictable and less seasonal climatic condition; both of which provided a long period for time for evolutionary diversification of various species.

• As per the Global Species Diversity data by the IUCN, there are about 1.5 million species declared.  Robert May, a population biologist, states that there are about 7 million species and only about 22% of it is discovered.
• Biodiversity is greatest in the tropical areas because of the warm and wet but a less seasonal climate, good precipitation level and does not experience extreme cold or dry conditions which provide a stable environment for increased biodiversity of species.
