Importance: Arable and livestock farming are primary food sources globally.
Economic Differences in the Primary Sector
MEDCs: Employ a small percentage of the population.
LEDCs: Employ a high percentage of the population.
Correlation: Higher economic development equals lower reliance on the primary sector.
