Why do vegetables like peas shrivel up when left outside for a few days?

Vegetables like peas shrivel up when left outside for a few days due to moisture loss through evaporation. When exposed to air, the water content within the peas evaporates, leading to dehydration and a reduction in turgor pressure, which is essential for maintaining their shape and firmness. Additionally, exposure to heat and sunlight can accelerate this process, causing further wilting and shriveling.
