Plants prepare their food by using raw materials like water, carbon dioxide and minerals.
The process of utilization of food by a living organism to obtain energy is called nutrition.
There are two modes of nutrition
Autotrophs or Autotrophic: - In this mode of nutrition organisms make their food themselves from simple substances. All green plants are Autotrophs (Auto means self and trophos means nourishment)
Heterotrophs or heterophobic: - Heterotrophic organisms are those who obtain food from other organisms. Since these organisms depend on other organisms for their food, they are called consumers. All animals and non-green plants like fungi come under this category.
