1. The "Poverty Line" is a benchmark or threshold used to determine the minimum level of income or consumption required for individuals or households to meet their basic needs, including food, clothing, shelter, and other essentials.
2.  It is often expressed in terms of calorie intake (calories consumed per day), which is a measure of the nutritional requirements necessary for maintaining a basic standard of living.
3. In the given scenario:
4.  The consumption of 2400 calories in rural areas and 2100 calories in urban areas represents the daily calorie intake of individuals in these regions.
   5. The poverty line is typically determined by considering the nutritional requirements and consumption patterns in different regions, with adjustments made for factors like location (rural or urban), family size, and age.

Therefore, the line drawn based on calorie consumption to define the minimum level of consumption required to escape poverty is known as the "Poverty Line." It helps identify individuals or households that may be experiencing poverty or are at risk of not meeting their basic nutritional needs.
