1. Water loss: Water leaves the plant body through transpiration. This results in water loss to the environment and the plant body. A palm tree in the desert loses 300-400 liters of water per day in the process of transpiration. A bhutra tree emits 200-300 liters of water per season (3-4 months).
2. Energy loss: Plants waste a lot of energy for respiration.
3. Death of the plant: In case of excessive irrigation, the plant dies due to lack of water.
