WebIn animals that contain coelomic fluid instead of blood, oxygen diffuses across the gill surfaces into the coelomic fluid. Gills are found in mollusks, annelids, and crustaceans. This common carp, like many other aquatic organisms, has gills that allow it to obtain oxygen from water. (credit: “Guitardude012″/Wikimedia Commons) WebThe ocean produces oxygen through the plants ( phytoplankton, kelp, and algal plankton) that live in it. These plants produce oxygen as a byproduct of photosynthesis, a process which converts carbon dioxide and sunlight into sugars the organism can use for energy. simply chic waxahachie

WebOct 27, 2024 · Answer: It's Oxygen. Explanation: Some abiotic factors, such as oxygen, are important in aquatic ecosystems as well as terrestrial environments. Terrestrial animals obtain oxygen from the air they breathe. Oxygen availability can be an issue for organisms living at very high elevations, however, where there are fewer molecules of oxygen in the air. WebTo know the main adaptations that pond organisms have evolved to get oxygen. The levels of oxygen in water are significantly lower than in the air we breathe and are affected by changes in temperature. Pond organisms exhibit a variety of adaptations which enable them to obtain oxygen from the water and to cope with a variable oxygen supply. [20 ... WebFish and many other aquatic organisms have evolved gills to take up the dissolved oxygen from water ( Figure 20.4 ). Gills are thin tissue filaments that are highly branched and folded. When water passes over the gills, the dissolved oxygen in water rapidly diffuses across the gills into the bloodstream. simply chic waxahachie tx
