Final answer:
The correct answer to how a family can derive food from rice paddies other than rice is fishing (a). Aquaculture in rice paddies offers protein through fish, which also assist in pest control and reduce disease risks.
Step-by-step explanation:
In response to the question of how else a family might derive food from rice paddies aside from the rice itself, the answer is: a) Fishing. Rice paddies offer an aquatic environment that can be used for aquaculture. Introducing fish species that eat insects into the rice paddies can help farmers reduce the use of pesticides and fertilizers while providing an important source of dietary protein. In addition, these fish can contribute to local economy as they can be sold at markets, and they also play an ecological role by consuming mosquito larvae, aiding in the reduction of mosquito-borne diseases.
Rice paddies also support intercropping, which means that some farmers practice the cultivation of fish alongside rice. This technique not only offers a source of food but also benefits the rice crop by controlling pests naturally, which could otherwise thrive in the wet, swampy conditions of rice fields.
