2. Click here to sign in with With the loss of predator and prey species it affects the life cycles in the food chain. Sea otters are considered a keystone species because of the crucial ecological role they play in maintaining the health and stability of the nearshore marine ecosystem. Otters rely on shellfish for food, and as ocean acidification decreases the shells of these shellfish, otters may starve as a result. __Otters take in oxygen and breathe out carbon dioxide. In the winter, when the water is frozen into ice, they create holes so they may rise to the surface to breathe. 5) No moving parts. CO2 and O2 have molecular structures that differ. Sea otters were hunted to near extinction during the maritime fur trade of the 1700s and 1800s. Also, a research held on water samples in the area showed that it contains high levels of chemicals that may indirectly kill the otters. What they found was surprising.

Public domain.) For gas exchange the otter uses some of its primary organs along with other parts of the body. Communities contained food chains with one, two or three trophic levels. The water becomes less acidic as a result. Comparing kelp density with otters and kelp density without otters, they found that " sea otters have a positive indirect effect on kelp biomass by preying on sea urchins, a kelp grazer." The premise of the sharks and oxygen claim is as follows: A) Sharks, many of which are apex predators, are important in regulating marine food webs; B) Phytoplankton, which create oxygen through photosynthesis, are in marine food webs; C) Therefore, without sharks, phytoplankton populations will crash and we won't have any more oxygen and we . Besides this, threatened events such as shipping and drilling oil across the Pacific and along coastal areas; the California sea otters is vulnerable to oil contamination. These combined energetic demands have been implicated in the poor body condition and increased mortality of female sea otters nearing the end of lactation along the central California coast. "I was pretty shocked," Estes says. Email: fedayiaksoy@hotmail.com This leads to an increase in turf algae growth, which then displaces the kelp. Kelp can be thought of as an excellent carbon sequestration agent because of its photosynthesis. Oxygen toxicity can cause seizures, respiratory distress, and even death. However . 30 seconds. (7)In some areas, Sea Otters have been reintroduced, in other areas they were never removed, and in others they. The otter-kelp link could be worth between $205 million and $408 million on the European Carbon Exchange, according to one study. in Interaction with kelps & sea otters). 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 primary predators of kelps. "I was pretty shocked," Estes says. However, the student later learns that Organism W's cells do not contain chloroplasts. Explain how energy is transferred through t The marine mammals consume on average one-fourth of its weight daily including sea urchins, which are vital to support the kelp forests. Sea otters are top predators that feed on a large diversity of marine invertebrates, consuming large quantities of prey items including sea urchins, an invertebrate grazer able to control the spatial extent and productivity of kelp forests.

They could start to feel dizzy and disoriented, and they could even lose consciousness. (4) Red Abalone populations have declined drastically, to the point of the abalone fishery collapse. The urchins consume kelp forests and expel carbon dioxide into the water, which is thought to be a significant contributor to the growth of CO2. Be sure to include at least five specific places that the carbon atom can be found as it makes its cycle. Unlike other marine mammals, they do not have a layer of blubber to help them keep warm. 12.10). Kelp forests are being developed as a way to reduce CO2 levels while improving water quality. However, they could be affected indirectly by their prey by changing their habitat. Effects of indirect actions and oxygen on relative biological effectiveness: estimate of DSB inductions and conversions induced by therapeutic proton beams Effects of indirect actions and oxygen on relative biological effectiveness: estimate of DSB inductions and conversions induced by therapeutic proton beams Additionally, their long generation time and low reproductive rate may limit their ability to adapt to changes in the environment.

Celeste Yarnall operates a holistic consulting practice for people and their pets specializing in feline and canine nutrition. Oxygen carrying capacity of marine North American otters is similar to other terrestrial mammals, including humans. 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. They live in riparian zones, which are common areas of the same size as beavers. The specific role of the sea otters in the eco-system is as follows; 1. It uses its lungs, esophagus, trachea, and mouth to inhale and exhale oxygen. The sea otters are keystone species, which means that their role in the environment affects it more than other species.

For example, beavers and otters may show few effects under good conditions, but during times of stress (e.g., extended severe weather), contaminants could have a more pronounced impact. The amount of warming is only a few degrees but it is enough to disturb the fragile balance of nature, which in turn will melt the polar ice, raise sea levels, cause violent hurricanes and endanger species such as polar bears.
