Carbon and Oxygen Interactions in Environmental Cycles Quiz

Plants convert carbon dioxide into organic compounds during photosynthesis.

Oxygen (O2) is not a greenhouse gas.

Carbon fixation is the process by which carbon is transferred from the atmosphere to the biosphere through photosynthesis.

Hemoglobin (Hb) is responsible for transporting oxygen in the bloodstream of animals.

Nitrous oxide (N2O) is a greenhouse gas that is more potent than carbon dioxide but less abundant.

Most of the Earth's ozone resides in the stratosphere.

The primary source of atmospheric carbon dioxide is the burning of fossil fuels.

Nitrogen dioxide (NO2) is a common greenhouse gas and an important component of smog.

The chemical formula for ozone is O3.

Decomposition involves the breakdown of organic matter by bacteria and fungi, releasing carbon back into the atmosphere.

The process by which carbon returns to the atmosphere from the Earth's surface is called respiration.

Coal mines are not a sink for carbon dioxide.

Deforestation contributes the most to the release of carbon dioxide into the atmosphere.

Stratospheric ozone depletion is not a feedback mechanism related to carbon dioxide in the atmosphere.

Increased carbon dioxide levels in the atmosphere can lead to more intense heatwaves.
