Answer: Crop Production and Storage.
Explanation: Commercial agriculture consists of raising food for trade and profits, while subsistence agriculture focuses on crop production and storage, by farmers, who use it for their subsistence. This type of cultural activity is carried out in order to collect the greatest amount of crops for it to last, taking into account that there are availability of such important elements as the tools and the optimization of the soil they use, since unfortunately only harvest is produced once a year.
