Answer 2

Carbon is the macronutrient which plays a key role in food production and in the normal growth of the plant. In the words of Emanuel Epstein, a macronutrient is defined as a nutrient without which a plant fails to complete a normal cycle.

Boron and Copper also play an important role in plant growth but are required in less quantity as compared to Carbon.

Carbon is one of the 17 macronutrients for plants.
