Which of the following impacts does overwatering NOT cause?

Overwatering leads to several issues that negatively affect plant health, but increased nutrient absorption is not one of them. When plants receive too much water, their roots can become waterlogged, leading to a lack of oxygen in the soil. This anaerobic condition can hinder the roots' ability to absorb nutrients effectively, often resulting in nutrient deficiencies rather than an increase.

Additionally, overwatering contributes to root rot, as excessive moisture promotes fungal growth that damages the roots. This also leads to plant suffocation, as roots require oxygen to function properly. Furthermore, soil erosion can occur in extremely saturated conditions where the soil structure becomes unstable and begins to wash away.

In essence, while overwatering can lead to many detrimental effects, enhancing nutrient absorption is not one of them. The correct response identifies that overwatering does not contribute positively to plant health by increasing nutrient uptake.
