Question

Carbon is available to crop plants in the form of

• A. Amino acids
• B. Carbon dioxide
• C. Elemental carbon
• D. Carbonates

Answer 1

The correct option is B Carbon dioxide

Plants prefer carbonates in the soil for their better growth. Alkaline soils will have more carbonates. The natural cause is the presence of soil mineral producing sodium bicarbonate and sodium carbonate upon weathering. From carbonates, more supply of carbon is available for the plants. It thus influences the photosynthesis process in plants.

So, the correct answer is option D.
