Concept:Subsistence agriculture is a system where farming is done primarily to feed the farmer's own household, not for commercial trade or high profit.
Explanation:In subsistence agriculture, the farmer cultivates crops and keeps animals mainly for family consumption.
Because production is targeted at meeting only household needs, the output is generally small.
Any excess produce after feeding the family is minimal, meaning the surplus produced is small.
Yields are not usually high, no significant savings are made, and the farm sizes are typically small.
Thus, the defining feature of subsistence agriculture is the very small amount of surplus available for sale or storage.
Answer:B. Surplus produced is small.
