The total population per net cultivated area of a country refers to its ______.

physiological density

The correct answer is Option (1) → physiological density

The total population per net cultivated area of a country refers to its physiological density.

Here's a breakdown of the terms:

• Physiological Density: This refers to the number of people per unit area of land suitable for cultivation (net cultivated area). It essentially indicates the pressure of population on the available agricultural land.
• Net Cultivated Area: This is the total land area that is actively used for growing crops. It excludes barren land, fallow land, and land used for non-agricultural purposes.

Therefore, physiological density provides a better understanding of the strain on a country's agricultural resources compared to just looking at total population density.
