Potato and carrot plants store a lot of starch in their roots. 6 hours ago. Those organisms which can not make food themselves by the process of photosynthesis and take food from green plants or animals, are called heterotrophs (and their mode of nutrition is called heterotrophic). On the basis of their modes of nutrition, all the organisms can be divided into two main groups: Those organisms which can make food themselves from simple substances (like carbon dioxide and water) by the process of photosynthesis, are called autotrophs (and their mode of nutrition is called autotrophic). chlorophyll.
