Explanation:

Indus Valley Civilization
It flourished around 2,500 BC, in the western part of South Asia, in contemporary Pakistan and Western India. It is also known as Harappan Civilization.
The Archaeological Department of India carried out excavations in the Indus valley wherein the ruins of the two old cities - Mohenjodaro and Harappa were unearthed in the 1920s. The Harappans were very well familiar with the manufacturing and use of Bronze. The civilization mostly situated near the flood plains, produced sufficient food grains like wheat, barley, rai, peas, sesame, lentil, chickpea and mustard.
Food of Harappans:
The archaeological evidence from Indus Valley sites (c. 3300 BC to 1300 BC) in present-day India and Pakistan suggests that a purely vegetarian meal will not provide a complete picture of what the Harappan people ate. Evidence of animal food consumption: From the quantity of bones left behind, animal foods were consumed in abundance: beef, buffalo, mutton, turtles, tortoises, gharials, and river and sea fish.
