The increase in temperature leads to greater activity so that there is an accelerating effect. Oxygen Bacteria are the only organisms that do not necessarily require oxygen. Some need it to survive, some do not need it but can survive in it, and others are killed by oxygen. Almost all fungi require oxygen for growth so that its low solubility in water prevents them from growing more than a short distance below the surface of still water. For this reason wood does not rot when submerged in water.
All animals require oxygen whether they obtain it from air or water.
Both become dormant without necessarily dying when the moisture content drops. Land animals require access to water at intervals but, except for termites, do not need high humidity to grow. Molluscs and crustaceans must live in a water environment, not so much for the water itself but because their oxygen-absorbing organs only function in water. Some are adapted to live in the tidal zone where they are exposed to air for several hours without injury. Light Light is indispensable for the continued existence of chlorophyllous plants, but is not immediately essential for the lower forms of plants or for animals.
