What is the Mode of Nutrition in Human Beings?

Human beings are classified as heterotrophs, which means that they obtain their nutrition by consuming other organisms. Specifically, humans are omnivores, which means that they obtain their nutrition by consuming both plant and animal-based foods.

Human nutrition involves the intake of food through the mouth, where it is broken down by mechanical and chemical digestion in the gastrointestinal tract. The food is then absorbed by the small intestine, where the nutrients are transported to various parts of the body through the bloodstream. The nutrients are then assimilated by the body for energy, growth, and repair.

The main nutrients required by human beings include carbohydrates, proteins, fats, vitamins, minerals, and water. Carbohydrates provide the body with energy, while proteins are used to build and repair tissues. Fats are used as a source of energy and for insulation, while vitamins and minerals are essential for maintaining proper bodily functions.

In summary, the mode of nutrition in human beings is heterotrophic and involves the intake and breakdown of food for the absorption of nutrients that are used for energy, growth, and repair.
