Nutrition
Nutrition is the process where an entity takes food and utilizes it for energy. It is a pivotal biological process that helps living beings to obtain their energy from various sources.
Nutrients are the substances which provide nutrition based on body requirements.
Mode of nutrition varies from one species to another. All green plants exhibit autotrophic nutrition as they synthesize their food by the process of photosynthesis, using light, carbon dioxide and water.
Plants are autographs, they have an autotrophic mode of nutrition. They perform photosynthesis to prepare their own food. Animals are grouped into a heterotrophic mode of nutrition, as they depend on plants for food. All vertebrates, including humans and some unicellular organisms such as amoeba exhibit the holozoic mode of nutrition.
