NEET BIOLOGY

Detailed explanation-1: -A one-carbon compound with formula CO2 in which the carbon is attached to each oxygen atom by a double bond. A colourless, odourless gas under normal conditions, it is produced during respiration by all animals, fungi and microorganisms that depend directly or indirectly on living or decaying plants for food.

Detailed explanation-2: -Animals exhale CO2 while plants use it in photosynthesis. Carbon dioxide is a gas at standard temperature and pressure, which exist in the Earth’s atmosphere. Carbon dioxide is exhaled by animals and utilized by plants for photosynthesis. It is also an important greenhouse gas.

Detailed explanation-3: -Carbon dioxide is a colourless, odourless gas, denser than air that occurs naturally in the earth’s atmosphere. It is slightly soluble in water, forming carbonic acid.

Detailed explanation-4: -Carbon dioxide is a chemical element that can be found in the atmosphere. At room temperature, it is a gas. It has one carbon atom and two oxygen atoms. When people and animals exhale, carbon dioxide is released. It is a greenhouse gas that is found in low concentrations in the Earth’s atmosphere.

Detailed explanation-5: -Carbon Monoxide is a colorless, odorless, tasteless, highly toxic gas that is undetectable to the human senses. It is a by-product of combustion, present whenever fuel is burned from kerosene, charcoal, diesel fuel, wood, gasoline, natural or liquefied petroleum (LP) gas, coal, propane, oil, methane, and tobacco smoke.
