NUTRITION -

Nutrition is the process of taking in food and converting it into energy and other vital nutrients required for life.”Nutrients are the substances which provide energy and biomolecules necessary for carrying out the various body functions. All living organisms need nutrients for proper functioning and growth. But they show divergence in how they fulfill this demand. Some animals feed on simple inorganic compounds to meet their nutrient requirement, while others utilise complex compounds. The mode of nutrition varies from one species to another.

Types of nutritions -

There are two modes of nutrition:

1. Autotrophic – Plants exhibit autotrophic nutrition and are called as a primary producer. Plants synthesis their food by using light, carbon dioxide and water.

2. Heterotrophic – Both animals and human beings are called heterotrophs, as they depend on plants for their food.

DIGESTIVE SYSTEM -

Various organs of Human digestive system in sequence are: Mouth, Oesophagus (or Food Pipe), Stomach, Small Intestine and Large Intestine. The glands which are associated with this system are: Salivary glands, Liver and Pancreas. The human alimentary canal runs from mouth to anus and is about 9 metres long tube.
