Question

Choose the feature not associated with organism found in tropical deserts

• A. Small body size
• B. Large surface area relative to their volume
• C. Large body extremities
• D. Small surface area relative to their volume

Answer 1

Answer: (A)

Small body size

Tropical desert areas are those where there is scarcity of water and extensive heat. Organisms in those areas adapt to survive in that ecological condition. Adaptations like thorns and succulents in flora helps the plants to survive without plenty of water. The leaves and stems undergo modification to conduct photosynthesis in less available water. Animals like frogs, rabbits, snakes, camels, etc. also go through modification in their characteristics to ensure their survival. Large surface of an any organism can lead to radiation of more body heat per unit of mass which can be fatal. Hence, such adaptations is not seen in organisms present in tropical desert.

So the correct option is 'large surface area relative to their volume'
