Removing carbon dioxide from the atmosphere will play a necessary role in preventing rising temperatures and future climate catastrophe. Change in temperature will reduce food sources in sea otter habitat, which will affect otter populations in a negative way. The reading passage tries to give some reasons to show that the number of sea otters, a small mammal living along the western coast of North America, has significantly declined because of the environmental pollution. 4. The energy expended for . Explain how energy is transferred through t According to the findings of a study, increasing the number of animals in an ecosystem may reduce its ability to absorb carbon. This is an example of mutualism because both organisms benefit from each other. How to balance the interests of fishermen with the need to support the recovery of sea otters has been debated back and forth, often failing to take into account the full scope of the problem, Estes says. This molecule is essential for life on Earth because it is used by plants and animals to generate energy. Sea otters help in preserving the kelp forests that grow underwater. 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. Sea otters are important nearshore ecosystems such as kelp forests and estuaries because they are top predators. Veterinarians examine a sedated sea otter. OH, 1 O 2, O 2 and H 2 O 2 generated from CAP have better antimicrobial ability than mimicked solution of mixture of single ROS type, but the reason is not clear. Q.

Water also absorbs oxygen released by aquatic plants during photosynthesis. CO2 and O2 are two molecules that are important in chemistry. When sea otters are exposed to high levels of oxygen, they may experience a condition called oxygen toxicity. Oxygen toxicity can cause seizures, respiratory distress, and even death. Modelling Southern Ocean ecosystems: krill, the food-web, and the impacts of harvesting. Without sea otters, sea urchins can overpopulate the sea floor and devour the kelp forests that provide cover and food for many other . Sea otters eat kelp to help keep the sea urchin population balanced, and kelp is a component of kelp. 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. drinking too much being redefined as "alcoholism" Further studies have also shown that the population density of sea otters affects seaweed biodiversity as well.

Specifically, they depend heavily on sea ice-dependent prey such as seals. Mason (1989) suggested that otter populations with PCB values of 50 ppm (lipid in liver) or more should be declining. In sea otters, the large lungs also are a significant (40%) source of oxygen during a dive. Studies have shown that kelp forests enhance the underwater environment, providing a suitable habitat for fishes. Kelps and macroalgae also contribute to oxygen generation by photosynthesis, which is a necessary step in the growth process.
