However, they could be affected indirectly by their prey by changing their habitat. Is that sea otter stealing your lunch -- or making it? of homrone x. surefire led conversion head; bayou club houston membership fees. In animals, oxygen is used to breathe, allowing them to use it for cellular respiration and to produce energy and carbon dioxide. The declining kelp beds in California in the mid 1900s propelled the Kelp Habitat Improvement Project, whereby attempts were made to eliminate sea urchins that are, Southern sea otter lives in kelp forests (a type of seaweed) along the Pacific coast, mainly off the coast of California. Abiotic factor Direct effect on otters Indirect effects on other species in food chain The temperature of the water wouldn't Cold temperatures don't allow for the Sea have too much of an effect on the otter otter's food source to be abundant Temperature Has no effect on Otters It lets other sea animals breathe Oxygen Otters breathe out carbon . answer choices. The relative importance of a water-repellent fur was assessed by changes in oxygen consumption and in body and subcutaneous temperatures before and after oiling and washing in 15 C water. Photo by the National Park Service. . Water clarity can affect sea otters in a number of ways. It starts with vast areas of kelp forests that, through photosynthesis, absorb atmospheric CO2 and release oxygen into the air.Mar 29, 2016 Do sea otters need oxygen? Frontiers in Ecology and the Environment, Provided by In the winter, when the water is frozen into ice, they create holes so they may rise to the surface to breathe. Sufficient DO is essential to growth and reproduction of aerobic aquatic . In general, there are two possibilities. SUMMARY. In addition, it shows the controversy surrounding the No Otter Zone. They can kill animals or plants that they touch, and they also are dangerous to humans who breathe their fumes or get them on their skin. Wind is a major abiotic factor in the kelp forests. Neuro spine Super Speciality Clinic - Above Apollo Pharmacy, Bangarpet Circle, Kolar - Bangarpet Road, Kolar Town. Some of the micro-organism are not single cells how are they arranged?
