Answer: the correct option is B( slash and burn farming).
Step-by-step explanation:
The rain forest is dense and made up of many types of broad- leave trees that are mostly evergreen. The trees form three layers or strata. The treetops form a thick canopy that prevents sunlight from reaching the forest floor. As a result, the vegetation on the forest floor is sparse. Therefore, for farmers to achieve a successful crop yield, a practice for clearing land for farming known as slash and burn farming method is used.
The slash and burn method is used in rain forest where an area is selected and the vegetation is cut down and burnt. This is to obtain a field usually called swidden that can be used for farming. After slashing( cutting) down the vegetation, it is allowed to dry and burnt. This method makes the soil fertile only for a short period of time and as a result farmers are forced to allow the farmland to fallow to renew it's fertility. One major disadvantage about this method is that it takes a long period of time(5 -15 years) to allow the land regain its lost nutrients and this can grossly interrupt both the economic and financial benefits of a farmer.
