Answer 2

Answer :

Cambridge English Dictionary defines 'heterotroph' as 'a living thing that gets its food from other plants or animals.'

Cambridge English Dictionary defines 'autotroph' as 'a living thing that can make its own food from simple chemical substances such as carbon dioxide.'

The number of heterotrophs found in desert regions is smaller. This is because in desert regions the number of autotrophs is less and this provides less number of sources of food to the heterotrophs which, in turn, affects the food chain. Apart from this, the harsh climatic conditions and less amount of water are also important factors that govern the number of heterotrophs in desert areas.

On the other hand, heterotrophs are found in greater numbers in the sea. This is because the sea abounds with a large number of autotrophs which are necessary sources of nutrition to the heterotrophs. The sea also provides an optimum temperature, suitable climatic conditions and plenty of water that contribute to the larger number of heterotrophs.
