What The three most important crops known as the three sisters which were essential for the Pilgrim's survival were?

The three most important crops known as the "three sisters" are corn, beans, and squash. These crops were essential for the Pilgrims' survival because they complemented each other in growth and nutrition. Corn provided a tall structure for beans to climb, beans enriched the soil with nitrogen, and squash spread along the ground to prevent weeds and retain moisture. This sustainable agricultural practice was crucial for the Pilgrims' food security.
