Birds
Birds are organisms which utilize a one-way air flow through their lungs to maximize air flow efficiency and <span>oxygen consumption
</span>The process of respiration is essential in the oxygen/carbon dioxide cycle. Respiration removes OXYGEN <span>from the atmosphere and produces and releases </span>CARBON DIOXIDE to the atmosphere.answer is letter D.
<span>Respiration driven by a mechanical series called inhalation and exhalation. We inhale or breathe in oxygen and exhale or breathe out carbon dioxide. </span>
