Animals use various mechanisms such as lungs for gas exchange, gills for aquatic respiration, digestive systems for nutrient absorption, and skin for diffusion of gases and wastes. Additionally, animals have specialized structures like alveoli in lungs, villi in intestines, and capillary networks to increase surface area for efficient exchange of materials. Some animals also use specialized respiratory pigments like hemoglobin to enhance the transport of oxygen.
In an aquarium, aquatic plants release oxygen through photosynthesis during the day when exposed to light. Fish and other aquatic animals then use this oxygen for respiration. In return, the animals release carbon dioxide into the water through respiration, which the plants uptake during photosynthesis to produce oxygen again. This creates a continuous cycle of oxygen and carbon dioxide exchange in the aquarium.
Many aquatic animals, such as some species of copepods, krill, and mollusks, feed on diatoms. Additionally, some fish species consume diatoms as part of their diet. These animals play a role in controlling diatom populations in aquatic ecosystems.

As aquatic matter dies and settles in the pond, the microbes use up the oxygen as they decay.
A rocket on there tail or back lol it is true though
Marine is used as an adjective when it is describing something found in or produced by the sea. (Example: marine life, marine plants) Aquatic is of or relating to water. (Example: aquatic sports, aquatic animals, aquatic plants)
What's true is that no animals live on the Antarctica, but that a few sea birds and aquatic mammals use the beaches in Antarctica for breeding.
Increased level of nutrients result in growth of algae in the water.These algae use up all the oxygen in water and form a layer on the water not allowing oxygen to enter.Therefore the aquatic animals die because they don't get oxygen.
Generally the body parts used for breathing (exchanging gases with the atmosphere for respiration) are:lungs in most larger animals (mammals, reptile, birds)gills in aquatic animals (fish, amphibians, cephalopods)diffuse tracheal systems (insects)some animals use secondary methods of breathing as their gills or lungs are not sufficient for their needs (animals such as frogs and eels) they use their skin to supplement the gas exchange
Oxygen is recycled in an aquatic environment in much the same way as it is on land. Phytoplankton, diatoms, seaweeds, and other underwater autotrophs use the sun's light to perform photosynthesis and release some of the oxygen produced in this process as a waste product. That oxygen is breathed in by aquatic animals and these animals exhale carbon dioxide because of respiration, which is necessary in the photosynthesis process by the autotrophs.
Some animals that use filter feeding to obtain food include baleen whales, manta rays, and sponges. These animals passively capture food particles from the water by filtering them out with specialized structures or mechanisms.
yes,some animals most of them don't (:
yes
I love to look at all the different types of aquatic life.
