The term 'carbon fertilization' best describes which one of the following phenomena?

Question

Accepted Answer

A. Increased plant growth resulting from a rise in the atmospheric concentration of carbon dioxide. Carbon fertilization refers to the increased rate of plant growth that results from a higher concentration of carbon dioxide in the atmosphere, since carbon dioxide is a raw material plants use in photosynthesis. It is not about adding compost to soil, capturing and storing carbon dioxide underground, or funding afforestation through carbon credits, all of which are separate concepts, ruling out the other options. Hence option A correctly describes what the term means.
