Question

One of the following statements is incorrect with reference to biodiversity. Identify it.

• A. Biodiversity increases from higher altitudes to lower altitudes.
• B. Depletion in genetic diversity of crop plants is mainly due to introduction of better varieties with high yield and disease resistance, etc.
• C. The richest reservoirs of animal and plant life with few or no threatened species are called hotspots.
• D. Biodiversity decreases from equator to polar regions.

Answer 1

The correct option is C The richest reservoirs of animal and plant life with few or no threatened species are called hotspots.

The large areas which contain exceptional concentrations of plant endemism and are experiencing very high rates of habitat loss are called ecological hot spots. Thus, they have a very high number of threatened species. These are also known as biodiversity hotspots. 2.3% of the Earth's land surface is represented by them. Currently, 36 biodiversity hot spots exist in the world.

So, the correct answer is 'The richest reservoirs of animal and plant life with few or no threatened species are called hotspots'.
