The effect is that less hemoglobin is available to carry oxygen to the tissues. ", More information: In the 2015 study, Nicholson et al. Scientists know that some kelp does end up in the deep ocean; how much, though, is difficult to estimate. As a result, when oxygen levels are reduced, the net primary production (NPP) of organic matter that supports the food web and ecosystems may be hampered. __Warmer water is more optimal for otter survival. Sea otters (Enhydra lutris) have the highest mass-specific metabolic rate of any marine mammal, which is superimposed on the inherently high costs of reproduction and lactation in adult females. Indirect effects of contaminants in aquatic ecosystems. They have lungs and breathe air. "I was pretty shocked," Estes says.
