The soil is rich source of which of the following?
I. Nitrogen
II. Phosphorus
Show answer & explanation
Correct answer: C
Explanation
Correct Answer:
Option 3: Both I and II
Explanation:
Soil serves as the primary source of essential nutrients for plants, containing both nitrogen and phosphorus in abundance. Nitrogen aids in plant growth, leaf development, and chlorophyll synthesis, while phosphorus plays a crucial role in root development, energy transfer (ATP), and the formation of flowers and fruits. These elements are available in the soil naturally—as well as through organic decomposition—and are also supplemented in agriculture through the use of fertilizers. Therefore, both statements are correct.
