Answer:
The analogy of growing corn suggests the idea of working hard and recognizing your worth and who you are while the plot of ground conveys the idea of being 'self-reliant' and believing in one's actions.
Step-by-step explanation:
The question is asked in the context of Ralph Waldo Emerson's most acknowledged essay titled 'Self-Reliance' which primarily focuses on preaching the idea of believing in one's self and chasing one's own thoughts and actions. He uses a variety of metaphors to throw light upon this idea. The metaphor of corn helps him to emphasize the significance of working hard and believing in your own actions, thoughts, and individual self instead of blindly following the rat race. The plot of the ground suggests the firmness and determination to stand by your own actions and keep growing and enhancing knowledge(through your toil) on your own 'plot of ground'(thoughts).
