Answer: Diseases that are caused by the lack of some particular nutrient in a person's diet are called deficiency diseases.

Vitamin A leads to Night Blindness
Vitamin C leads to Scurvy
Vitamin D leads to Rickets
Communicable diseases are those diseases which spread by air, by water by direct contact.
