If they have gills the animal will take in oygen from the water it breathes...or if it is a mammal that lives underwater it will normally have a blow hole or such which it will rise & breathe in air.
Aquatic organisms need oxygen to survive
Yes, fish and other aquatic life need to extract oxygen out of the water using gills.
gills
Yes, organisms in aquatic environments typically need adaptations for buoyancy, oxygen acquisition through gills or other specialized structures, and ways to conserve body heat as water conducts heat away faster than air. Land organisms, on the other hand, need adaptations for walking or flying, regulating water loss, and managing body temperature in varying atmospheric conditions.
The relationship between water temperature and dissolved oxygen levels in aquatic ecosystems is crucial. Warmer water holds less oxygen, which can lead to lower oxygen levels in the water. This can be harmful to aquatic organisms, as they need oxygen to survive. Low oxygen levels can result in stress, illness, and even death for fish and other aquatic life. Therefore, maintaining a balance between water temperature and dissolved oxygen levels is essential for the health of aquatic ecosystems.

Yes, gills take in oxygen from water. As water flows over the gill membranes, oxygen diffuses from the water into the bloodstream of aquatic animals, while carbon dioxide is expelled from the blood into the water. This process allows fish and other aquatic organisms to efficiently extract the oxygen they need for respiration.
Dissolved gases in water are important for aquatic organisms to respire and survive. Oxygen, for instance, is necessary for the survival of fish and other aquatic organisms, while carbon dioxide is essential for photosynthesis in aquatic plants. Additionally, gases like nitrogen help support the ecosystem by providing essential nutrients for growth.
Excess oxygen in water can be harmful because it can lead to faster oxidation and degradation of organic matter. This can affect aquatic organisms by decreasing the availability of oxygen they need to survive, leading to negative impacts on the ecosystem.
A snake breathes through its nose, since they have lungs. Even fully aquatic species need to come up for air.
All organisms need oxygen to live.
These organisms do not need oxygen. They are called anaerobes.
