Biodiversity Conservation Methods

Question

One of the following statements is incorrect with reference to biodiversity. Identify it.
Depletion in genetic diversity of crop plants is mainly due to the introduction of better varieties with high yield, disease resistance, etc.
Biodiversity increases from higher altitudes to lower altitudes.
The richest reservoirs of animal and plant life (species richness) with few or no threatened species are called "biodiversity hotspots".
Biodiversity decreases from the equator to polar regions.

Verified by Toppr

The correct option is C The richest reservoirs of animal and plant life (species richness) with few or no threatened species are called "biodiversity hotspots".
Biodiversity hotspots are areas which are rich in aminal or plant species or high degree of biodiversity.
They are determined by mainly three factors:
(i) A number of species/species diversity.
(ii) The degree of endemism.
(iii) The degree of the threat to habitat due to its degradation and fragmentation.
Thus, the correct answer is option (C).
