Select the reasons why tropical regions have more biodiversity than temperate regions . 1. Tropical latitudes have remained relatively undisturbed for millions of years . 2. Temperate environments, unlike tropical ones , are less seasonal , relatively more constant and predictable . 3 . Temperate regions were subjected to frequent glaciations in the past. 4. There is more solar energy available in the tropics which contributes to higher productivity .

Assertion (A): There is more species biodiversity in tropical latitudes than in temperate ones. Reason (R) : Tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable.

What is so special about tropics that might account for their greater biological diversity? a. 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. Temperate environments, unlike tropical ones, are less seasonal, relatively more constant and predictable. Such constant environments promote niche specialization and lead to a greater species diversity. c. There is more solar energy available in the tropics, which contributes to higher productivity, this in turn might contribute indirectly to greater diversity.

Is it true that there is more solar energy available in the tropics ? Explain briefly.

Select incorrect statements w.r.t. greater biological diversity in tropics (A) Tropical latitudes have remained relatively undisturbed for millions of yeasrs and thus had a long evolutionary time for species diversification. (B) Tropical enviroments are more seasonal and less predictable than temperates. (C) There is more solar available which contributes to higher productivity.

Giving two reasons explain why there is more species biodiversity in tropical latitudes than in temperate ones.

Choose how many of the given statement are not correct about the Tropics ? (i) Greater species diversity compared to Temperate (ii) Subjected to frequent glaciations in the past (iii) Great seasonal variations are seen here (iv) Enviornment is relatively constant
