NEETBotanyBiodiversity and its Conservation
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In the Amazonian rain forest, the number of fish species is greater than the number of bird species. Reason (R): Tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable, which promotes niche specialisation. In the light of the above statements, choo
Options
- ABoth Assertion (A) and Reason (R) are true and (R) is the correct explanation of (A).
- BBoth Assertion (A) and Reason (R) are true but (R) is not the correct explanation of (A).
- CAssertion (A) is true but Reason (R) is false.
- DAssertion (A) is false but Reason (R) is true.
Correct answer
B. Both Assertion (A) and Reason (R) are true but (R) is not the correct explanation of (A).
Step-by-step solution
Assertion (A) is true: According to the biodiversity data of the Amazonian rain forest, there are 3,000 species of fishes and 1,300 species of birds. Hence, fish species outnumber bird species. Reason (R) is true: Tropical environments are less seasonal, relatively more constant and predictable compared to temperate regions. This constancy promotes niche specialisation and leads to greater species diversity. However, Reason (R) explains the overall high biodiversity in tropical latitudes, but it does not specifical
