प्रश्न
The number of heterotrophs found in desert regions is smaller. However, they are found in greater numbers in the sea. Why is this so?
उत्तर
The conditions in deserts are extremely difficult for survival of organisms. Not all kinds of organisms can survive in such harsh climatic conditions, which means there are only few types of organisms which would be found in this region. Since, there are not many kinds of plants and animals which are found in this region, heterotrophs would not be able to survive and would die of starvation. That is why less heterotrophs are found in desert areas. However, in case of a habitat like sea, there are plenty of organisms which are found in the region ranging from aquatic plants, to small fishes to big fishes. It is an environment which supports the survival of heterotrophs, and thus more heterotrophs are found in this region.
