However, the methods they both use are very different. Autotrophic nutrition is in its simplest terms is being able to feed oneself and synthesise ones own food from simpler molecules. Hetrophic nutrition however, is the opposite, unable to synthesise its own food. Immediately, one notices which of the categories each the plants and animals fall into. It is important to stress that Autotrophic nutrition lays down the building blocks of life and provides complex organic molecules for the consumption of Hetrophic organisms.

Essentially plants survive on the products of photosynthesis and...
