Greeb plants are autotrophs, they do prepere their own food material.
The word 'auto' means 'self' and 'trophe' means 'nutrition'. Thus, autotrophic means 'self-nutrition’. Green plants are able to prepare their own food from simple raw materials like carbon dioxide from the air, water from the soil and energy from the sunlight. This mode of nutrition where green plants make food themselves from simple substances is called autotrophic nutrition. Such plants are therefore called autotrophs.
Since animals lack chlorophyll they are incapable of manufacturing their own food. They have to depend directly or indirectly on plants for food. Animals are thus heterotrophic where ‘hetero’ means different.

All animals are heterotrophs, which means that they cannot make their own food as plants do. Rather, animals must obtain the energy, carbon, hydrogen, oxygen, nitrogen, and minerals they need by consuming other living things. Animals are also animate, which means that they are capable of movement. Movement requires a lot of energy, so animals generally require substantially more energy than plants do
.Most plants are able to use sunlight as their primary source of energy, in a process called photosynthesis. This process enables them to turn carbon dioxide from the air into food, which they can store and later break down to meet their energy needs. The carbon and oxygen which they need in order to build up their bodies ultimately comes from this carbon dioxide. Hydrogen comes from water, which they absorb through their roots. Plants split hydrogen (H) off from water (H2O) and emit the leftover oxygen into the air. This is good for us animals, because we breathe in oxygen and breathe out carbon dioxide. This cycle of oxygen and carbon dioxide between plants and animals ties together almost all of the living things on earth.
