Question

A large number of unknown species of plants and animals are believed to be present in

• A. Temperate forests
• B. Antarctica
• C. Deserts
• D. Tropical forest

Answer 1

The correct option is D Tropical forest

Tropical forest receives maximum sunlight which is a key factor in energy production by plants, thereby supporting a large number of plant species. Due to the availability of ample energy/food sources in the form of plants, animal, lives are supported. Thus, tropical forests are considered to carrying highest biodiversity and are expected to carry a large number of unknown species.

Temperate and taiga regions are characterised by chill winters with the temperature falling below freezing point. This poses necessity of the presence of special adaptations in living organisms to survive the harsh winters when sunlight is not available, thus these regions experience lesser biodiversity as compared to the tropical forest.

Antarctica region is characterised by the coldest climate with permanent snow covered surface and no direct sunlight thereby not supporting the growth of living organisms.

Therefore, the correct answer is option D.
