Explanation:
Detailed explanation-1: -Carbon dioxide is a heavy, odorless, colorless, faintly acid-tasting, and non-flammable gas (at room temperature) that is released during respiration, combustion, and by the decomposition of organic substances, which is then mostly absorbed from the air by plants in the process called photosynthesis.
Detailed explanation-2: -CO2 is colorless and odorless gas at normal room temperature. It is exhaled by humans and animals, and released in air by burning of fossil fuels and other organic substances. CO2 is consumed in photosynthesis in trees and green plants.
Detailed explanation-3: -During photosynthesis, plants absorb carbon dioxide from the air through stomata.
