Question

The number of heterotrophs found in desert regions is smaller. However, they are found in greater numbers in the sea. Why is this so?

Answer 1

1. In desert region due to scarcity of water and excess heat, very few cactus are found as autotrophs compared to sea. As autotrophs are less, number of heterotrophs dependent on autotrophs are smaller.

2. Whereas in sea due to greater numbers of autotrophs, greater number of heterotrophs are found.
