Question

the conversion of inorganic carbon to organic carbon is called carbon:

• conversion.
• sequestration.
• hoarding.
• fixation.

Explanation:

Carbon fixation is the biological process where inorganic carbon (e.g., CO₂) is converted into organic carbon compounds (e.g., glucose) by autotrophs like plants during photosynthesis. The other options do not specifically describe this process: conversion is too general, sequestration refers to storing carbon, and hoarding is unrelated to carbon cycling.

Answer:

D. fixation.
