Biodiversity and Conservation

Tropical regions show greatest level of species richness because A. Tropical latitudes have remained relatively undisturbed for millions of years, hence more time was available for species diversification. B. Tropical environments are more seasonal. C. More solar energy is available in tropics. D. Constant environments promote niche specialization. E. Tropical environments are constant and predictable. Choose the correct answer from the options given below.

  1. (A)A, C, D and E only
  2. (B)A and B only
  3. (C)A, B and E only
  4. (D)A, B and D only

The NCERT line that answers it

Verbatim line

Ecologists and evolutionary biologists have proposed various hypotheses; some important ones are (a) Speciation is generally a function of time, unlike temperate regions subjected to frequent glaciations in the past, tropical latitudes have remained relatively undisturbed for millions of years and thus, had a long evolutionary time for species diversification, (b) Tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable.

The answer appears as a continuous sentence in NCERT. This is that sentence.

How this line gives the answer

0, emb=1.0, combined=1.0). Verified: high — The span explicitly contains all four correct options (A, C, D, E) with their distinguishing biological facts: (a) matches option A about undisturbed time for diversification, (b) mentions less seasonal/constant/predictable environments matching E, states such constant environments promote niche specialization matching D, and (c) mentions more solar energy available in tropics matching C.
