Answer 1

Answer:

option 4) ............

Answer 2

Due to Water logging (4)All the above are correct. Air is expelled from in-between the particles of soil, Oxygen becomes unavailable to the roots of the plants and Plants respire anaerobically which produces alcohol and kills them.

Water logging:

• Soil that has been waterlogged has been saturated with water.
• When soil is frequently almost saturated with water, its air phase is constrained, and anaerobic conditions predominate, the soil may be deemed to be waterlogged.
• Waterlogging happens when there is too much water in the root zone of a plant, which reduces the amount of oxygen the roots can access.
• Waterlogging can significantly impede plant development and productivity and, in some cases, even result in plant death.
• High water intake from rain, runoff, interflow, an increase in groundwater, excessive irrigation, or flooding can produce water logging, a drainage issue.
• Low water outflow from low infiltration rates, poor hydraulic conductivity, and flat land can all contribute to drainage issues.

Importance of water logging:

• This temporary waterlogging is crucial because certain damages, such as oxidative stress, may intensify during the reaeration of tissues following a stressful period.
