Final answer:
Nathan is likely growing rice, which requires sowing, germination, and transplanting to flooded fields annually. Rice is categorized as a monocot, unlike eudicots like beans and cabbage.
Step-by-step explanation:
At a certain time of the year, when Nathan is sowing and transplanting, it is likely that he is growing rice. This is because rice cultivation often involves germinating seeds, allowing them to grow to a seedling stage, and then transplanting them to flooded fields.
This practice is depicted in Fig. 1, where it describes the propagation of rice as an annual that must be replanted each year. Moreover, rice is known as a monocot crop, as indicated in Figure 14.30, along with other cereals like wheat and bananas. In contrast, crops such as beans and cabbage are eudicots.
