Nutrition
Nutrition – The survival of all living organisms is due to several types of nutritive
processes. The process of nutrition involves ingestion digestion, absorption
and assimilation of food materials.
The composition of nutrients vary in different types of feeding. However, for all living organisms, the nutrient comprises the following organic and inorganic components.
They are carbohydrates, proteins, lipids, vitamins, minerals and water. Each
component has a specific functional role.
A well proportioned intake of nutrients depends on several factors such as stage of growth, sex, health condition, bodily activities and environmental situations.
