Moin took some soil and measured the concentration of nitrogenous compounds in it. He distributed the soil equally in two pots- P and Q which he placed in sunlight.
He planted 10 sunflower seeds in Pot P and allowed them to grow. He did not grow anything in the Pot Q.
After one month, he tested the concentration of nitrogenous compounds in both the pots.
What do you think was his observation?

The nitrogenous compounds in the Pot P will be depleted and the Nitrogenous compound in the Pot Q will have same amount of it.

Explanation:

Moin took soil and put into two pots. In one of the pot which he labelled P,planted sunflower seeds.

Whereas, the pot Q he left as it is with no plantation in it. The observation after few days will be that the level of nitrogen in the pot P will be less compared to the pot Q.

Nitrogen is one of the important micro nutrient which serves many important functions in the plant body. It is the main component of  chlorophyll and is important in enzyme synthesis.

Hence, pot P will have its nitrogen consumed by the plant and pot Q will have nitrogen in its soil.
