If the accumulation ratio in absorption of nutrients is greater than one, then it is known as

✅ Explanation: The accumulation ratio refers to the concentration of a nutrient inside a cell or tissue compared to its concentration in the external environment. When this ratio is greater than one, it indicates that the nutrient is being accumulated against its concentration gradient, which requires energy expenditure. This process is characteristic of active absorption, where transporter proteins actively move nutrients across the cell membrane.
📌 Other Options Explanations:
-Passive absorption: This involves the movement of nutrients down their concentration gradient without energy expenditure.
-Adsorption: This is the adhesion of molecules (like nutrients) to the surface of a solid or liquid.
