Answer:
They produce only enough to feed their family, and they have little left over to sell at a market.
Explanation:
Africa, in general, is a continent that has very low levels of development. In most of the countries, the primary economic sector dominates, with most of the people being engaged in agriculture (farming and herding). The manner in which most of the agriculture is done is at a subsistence level and very far away from being in a situation to boost the economies.
Subsistence farming is a type of farming where people engaged in it produce enough for the needs of their families, while it is very rare that they have any surplus to sell on the market and earn something. This type of agriculture is performed in a primitive manner, without the usage of modern mechanization, fertilizers, pesticides, etc. This results in a very low production of agricultural goods as they don't get the proper treatment to produce more.
