Question

The question consist of two statements – Assertion (A) and Reason (R). Answer these questions selecting the appropriate option given below:

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true, but (R) is not the correct explanation of (A).
• C. (A) is true, but (R) is false.
• D. (A) is false, but (R) is true.
  Assertion (A): Communities that comprise of more species tend to be more stable.
  Reason (R): A higher number of species results in less year-to-year variation in total biomass.

Hint:

Biodiversity ensures ecosystem stability by providing functional redundancy, where multiple species perform similar ecological roles.

Answer 1

The Correct Option is A

Increased species richness in ecosystems correlates with enhanced resistance to environmental disturbances, leading to more consistent overall biomass levels.
