Which term best describes carbon-containing nutrients usually produced by plants?

Explanation:
This question tests how we classify nutrients by carbon content. Carbon-containing nutrients produced by plants are organic compounds. Plants synthesize organic molecules—like glucose, starch, fats, and proteins—using carbon dioxide and water during photosynthesis, so these substances are described as organic nutrients. Inorganic nutrients, on the other hand, are minerals and simple ions that lack carbon-hydrogen frameworks. Minerals are essential too, but they are not carbon-based. So the best term for carbon-containing, plant-produced nutrients is organic.
