Answer 1

The steps of nutrition are:

• Ingestion – putting the food into the body through the mouth.
• Digestion – once the food reaches the stomach, it is converted into a soluble form.
• Absorption – after digestion, the nutrients are extracted from the food and absorbed in the small intestine.
• Assimilation – the nutrients are transferred to the different parts of the body via blood for the functioning of different organs.
• Egestion – excretion of the left-over matter as feces from the body.
