", More information: Also, too much sediment or other particles floating in the water absorb heat from sunlight. Ch. he chain. They note that markets have been established in Europe and the United States to trade carbon credits and thus inject an economic incentive into either reducing CO2 output or increasing CO2 sequestration. Kelp can grow pretty big in a year, but for a tree, it might take 50 or 100 years to grow to maturity, Estes explains. When they are in an environment with a lot of carbon dioxide, they will breathe more quickly to get rid of the excess. Several factors have led up to the collapse including Withering Syndrome, where the organism loses the ability to attach itself to rocks, making it more susceptible to predation, or the organism can eventually wither and starve to death. surefire led conversion head; bayou club houston membership fees.

Based on their calculations, the presence of otters increased the carbon storage of kelp forests by 4.4 to 8.7 megatonsequivalent to the amount of carbon found in the annual carbon dioxide emissions from 3 to 6 million passenger cars. Otters & the Carbon/Oxygen cycle The abundance of sea otters eat the sea urchins. 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. Monetizing the impact otters have on carbon sequestration reveals yet another layer of just how complex the issue is, and the studys authors point out that the sale of carbon credits may provide an avenue for offsetting monetary losses to shellfisheries caused by otters. Their productivity is on par with a tropical rainforest in terms of the amount of carbon they turn over in a year, says ecologist Chris Wilmers of the University of California, Santa Cruz, one of the studys authors. The main features of an OTTER is the ability to: 1) Move high volumes of water (between 30 to 500 M.G.D.) Kelp forests thrive best in nutrient-rich waters with temperatures ranging from 42 to 72 degrees Fahrenheit (5 to 20 degrees Celsius). Careers. The water must be clear so that sunlight can reach the ocean floor, where kelp thrives. "If ecologists can get a better handle on what these impacts are, there might be opportunities for win-win conservation scenarios, whereby animal species are protected or enhanced, and carbon gets sequestered," he said. Question 11. Abiotic Factor Direct effect on otters Indirect effects on other species in food chain Temperature Warmer water is better for the survival of otters. The carbon dioxide indirect effect on otters refers to the fact that carbon dioxide emissions can lead to ocean acidification, which in turn can negatively impact otters. Closed.
