They are a diverse group that include sea snakes, sea turtles, the marine iguana, saltwater crocodiles, penguins, pinnipeds, cetaceans, sea otters, manatees and dugongs.All known diving vertebrates dive to feed, and the extent of . effects of sea otters (-Crabs -Otters), and the direct effects of sea otters (Partial Cage Control and Open Control) on eelgrass communities (grazers and algal epiphytes) and This warms the water and decreases dissolved oxygen even further. Mon Sep 24 2012. how otters affect the Carbon/Oxygen cycle. The natural predator of the urchin is the otter. part may be reproduced without the written permission. This directly refutes the reading passage which states that predation was most likely the reason, since the bodies of the dead sea otters didn't wash on the shores.Secondly, the passage mention that the water samples that were extracted from the sea revealed the presence of chemicals. Otters rely on shellfish for food, and as ocean acidification decreases the shells of these shellfish, otters may starve as a result. While much is known about the direct effect that temperature can have on aquatic communities, less is known about its indirect effect via the temperature dependence of viscosity and temperature-dependent trophic interactions. Secondly, oil spills result in the death of sea otters. An estimated 3500-5500 otters from a total population of about 30,000 may have died as a direct result of the oil spill. Science 282, 473 . While much is known about the direct effect that temperature can have on aquatic communities, less is known about its indirect effect via the temperature dependence of viscosity and temperature-dependent trophic interactions. Here, she focuses on sea-ice dependent animals such as Polar Bears and Ringed Seals at Arctic. Our findings indicate that the overall effects of DSB induction and enzymatic DSB could intensify the tumor killing, while alleviate normal tissue damage when indirect actions are effectively interrupted. the increased numbers of decomposers. 120 seconds.

The presence or absence of sea otters influences marine ecology at the community-level. The otter also gets oxygen by poking its head out of the water and then taking deep breaths to take in all necessary oxygen. Otters are marine mammals that rely on a constant supply of oxygen to live. Additionally, their long generation time and low reproductive rate may limit their ability to adapt to changes in the environment. Kelp forests thrive best in nutrient-rich waters with temperatures ranging from 42 to 72 degrees Fahrenheit (5 to 20 degrees Celsius). The water becomes less acidic as a result. __Warmer water is more optimal for otter survival. Answer (1 of 3): Abiotic factors in an environment include such items as sunlight, temperature, wind patterns, and precipitation, could affect sea otters or any other animal if exposed to them adversely. The greater the number of CO molecules, the higher the percentage of hemoglobin turns into COHb (%COHb) and the greater the harm: We suffocate when the oxygen levels in our tissues drop too low.
