Show Hint
Carbon is the macronutrient which is an essential component of all organic compounds and is not obtained by plants from the soil.
- Nitrogen
- Carbon
- Phosphorus
- Magnesium
The Correct Option is B
Approach Solution - 1
Carbon is the macronutrient that is an essential component of all organic compounds and is not obtained by plants from the soil. Instead, plants obtain carbon from carbon dioxide (CO2) in the air through the process of photosynthesis. During photosynthesis, plants convert light energy from the sun into chemical energy stored in the form of organic compounds such as sugars, starches, and cellulose.
Hence, option B) Carbon is the correct answer.
Approach Solution -2
A macronutrient named 'Carbon' is an essential component of all organic compounds. Plants obtain carbon in the form of carbon dioxide (CO2) from the atmosphere, not from the soil.

In an experiment to determine the figure of merit of a galvanometer by half deflection method, a student constructed the following circuit. He applied a resistance of \( 520 \, \Omega \) in \( R \). When \( K_1 \) is closed and \( K_2 \) is open, the deflection observed in the galvanometer is 20 div. When \( K_1 \) is also closed and a resistance of \( 90 \, \Omega \) is removed in \( S \), the deflection becomes 13 div. The resistance of galvanometer is nearly:
