(N/A) $\Rightarrow$ Plants require water for essential metabolic processes such as photosynthesis,transpiration,and respiration. However,excessive watering leads to plant death.
$\Rightarrow$ When the soil is waterlogged,the water fills the spaces between soil particles,displacing the air (oxygen) that is normally present.
$\Rightarrow$ Consequently,the roots are deprived of oxygen,which is necessary for aerobic respiration. Without oxygen,root cells cannot function and eventually die.
$\Rightarrow$ Once the root cells die,the plant loses its ability to absorb water and essential mineral nutrients from the soil,leading to the gradual death of the entire plant.
