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.
That's where barnacles live, peeking out only when water covers them so they can filter food into their homes. This barnacle zone is the highest of the intertidal zones. Although they may look like mollusks with their shell-like covering, barnacles are actually crustaceans, related to lobsters, crabs and shrimp.They look like tiny shrimp in their larval stage, where they swim as members of zooplankton in the ocean.hat's where barnacles live, peeking out only when water covers them so they can filter food into their homes.
