WebFeb 13, 2024 · Insects breathe in oxygen and release carbon dioxide as a waste product. Because they do not have lungs, insects do not carry out a respiration process that is identical to that of humans. Insects are designed to take in oxygen under the specific conditions to which they are most frequently exposed. WebOxygen dissolves in water but at a lower concentration than in the atmosphere. The atmosphere has roughly 21 percent oxygen. In water, the oxygen concentration is much smaller than that. Fish and many other aquatic organisms have evolved gills (outgrowths of the body used for gas exchange) to take up the dissolved oxygen from water.
