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 much larger than sharks. The blue whale is the largest of all the mammals on Earth. When a whale weighs more than 100 tons, the shark weighs about 2,000 kg. Sharks hunt for their food. Whales do not have this hunting tendency. Plankton and krill are the food of whales.hale vs Shark. Whales are mammals and sharks are fish. When whales give birth to young ones, sharks lay eggs. Unlike the young sharks, young whales are fed milk. The whales raise their young ones whereas sharks do not.
