Question

Quizplus · Accepted Answer

Carbon dioxide (CO₂) plays a crucial role in various natural processes. It is removed from the atmosphere during photosynthesis as plants and other photosynthetic organisms use it to produce glucose. It serves as a source of carbon for autotrophs, organisms that can produce their own food from inorganic substances. CO₂ is returned to the atmosphere through respiration and fermentation as organisms break down sugars to release energy. Additionally, marine organisms use CO₂ to make calcium carbonate (limestone) for their hard shells, contributing to the carbon cycle.
