Question

Why do plants die when over-fertilized?

• A. As a result of dehydration
• B. Due to damage of walls of root hairs
• C. Due to blockage of nitrogenous ions
• D. Due to upsets in soil environment by poisonous soil bacteria

Answer 1

The correct option is A

As a result of dehydration

The correct option is A

Explanation of the correct option:

1. Plants die when over fertilized as a high amount of fertilizer concentration can cause damage to crops and can cause ecological problems such as soil salinization as well.
2. Soil salinization will eventually affect the absorption, transportation, and utilization of nutrients by plants, leading to dehydration and then, death of the plant.

Explanation of the incorrect option:

Option B:

Damage to root hairs occurs in case of overgrazing or any kind of natural calamity.

Option C:

Nitrogenous ions in the plants are blocked if the pH conditions are not met.

Option D:

Poisonous bacteria come in contact with the soil when harmful pesticides are used.

Final Answer: Plants die when over-fertilized as a result of dehydration.
