Answer 2

Deficiency disease is one that is caused by a shortage of important nutrients or dietary ingredients in the human body, such as vitamins and minerals.

Explanation: Examples of deficiency diseases include: Beriberi is caused by a shortage of vitamin B1, and anaemia is caused by a lack of iron in the body.

A long-term shortage of essential amines in our bodies causes vitamin insufficiency. A primary deficiency occurs when a person consumes insufficient amounts of vitamins, while a secondary deficiency occurs when a person's vitamin absorption is impaired owing to a problem. Diseases like beriberi and pellagra, scurvy, night-blindness are caused by vitamins deficiency.
