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 divided into two suborders â toothed and baleen whales â and each eats very different kinds of food. Toothed whales eat fish, squid, and other animals, while baleens eat plankton, krill, and other small creatures.rcas work tpgether to catch prey larger than themselves. Whale's eat a variety of foods, and their diets may have been impacted by humans. Humpbacks are one of the many whale species that feed on plankton. A blue whale can eat 8,000 pounds of food a day to store reserves for winter.
