Question

Passive absorption of minerals depends upon

• A. Humidity
• B. Temperature
• C. Temperature and metabolic inhibitor
• D. Metabolic inhibitor

Answer 1

The correct option is B Temperature

Passive absorption of minerals is a slow process which does not require energy. It is a physical process and hence depends upon the physical factors like temperature. Passive absorption occurs along the concentration gradient. High concentration of mineral has high pressure and low temperature that favours the flow of mineral from high to low concentration.

So the correct answer is 'Temperature'.
