The metabolic explanation of these processes is expressed in concepts like endogenous respiration (Gujer et al., 1999), death-regeneration (Dold et al., 1980), maintenance (Loosdrecht van and Henze, 1999) or predation (Moussa et al., 2005).xperimental evidence for the validity of the endogenous respiration model comes from Marais and Ekama (1976) . Using the OUR method, the value of b OHO was found to be 0.24 d â1 and independent from SRT in the range of 2.5â30 days. Similar results were obtained by van Haandel et al.
Whale barnacles attach themselves to the bodies of baleen whales during the barnacles free-swimming larval stage. Though often described as parasites, the relationship is an example of obligate commensalism, as the barnacles neither harm, nor benefit, their host. Elyse Â· 5 months ago. Thumbs up.
Whales are the largest animals that live on the planet. They are marine mammals that belong to the order of cetacea, which includes roughly 80 species of whales, dolphins, and porpoises. Many species of whales migrate long distances each year between feeding and breeding grounds. 2  Whales are divided up between baleen whales and toothed whales. 3  Baleen whales are filter feeders, feeding on the oceans smallest organisms like krill, while toothed whales feed on fish, squid, and other marine mammals.
