The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms
Explanation:
External respiration takes place in the lungs, where oxygen enters the blood and carbon dioxide enters the alveolar air. Internal respiration takes place in metabolizing tissues, where oxygen diffuses from the blood and carbon dioxide diffuses from the cells.
<h3>What is respiration?</h3>
Respiration is recognized as the movement of oxygen from the outside environment to the cells within tissues, as well as the removal of carbon dioxide in the opposite direction.
External respiration takes place in the lungs, where oxygen enters the blood and carbon dioxide enters the alveolar air.
Internal respiration takes place in metabolizing tissues, where oxygen diffuses from the blood and carbon dioxide diffuses from the cells.
Thus, in this way, external respiration and internal respiration are co-dependent.
