Important Questions on Organisms and Populations
Reason (R): Due to low atmospheric pressure at high altitude, the body does not get sufficient oxygen.
In the light of the above statements, choose the correct answer from the options given below.
Statement (S): Very small animals are rarely found in the polar regions.
Reason (R): Small animals have a larger surface area relative to their volume and tend to lose body heat.
The correct answer is

Given is a diagram representing the annual mean temperature and the annual mean precipitation in three biomes and on the planet. All the animals living in these biomes together can be largely grouped into two major classes 'Regulators' and 'Conformers'. Regulators are the animals that can regulate their body temperature and Conformers are those animals whose body temperature changes as per the environmental temperature. Assuming that these animals do not have any specialized adaptations, the correct statement would be
