Furthermore, countries such as the United States, Russia, and Canada have set up marine protected areas where activities such as dumping of waste and oil drilling are prohibited. Abiotic Factors that Affect Kelp Health, Density, and Population Nutrient Availability Not unlike terrestrial plants, kelp requires nutrients such as Nitrogen and Phosphorus to grow and reproduce. Diseases and infections also caused a decrease in population specifically when pet owners started dumping cat feces down storm drains and toilets. A biotic factor is any living component that affects another organism, including animals that consume the organism in question, and the living food that the organism consumes. Secondly, oil spills result in the death of sea otters. The Deep Sea Ecosystem: Life In The Dark And Cold Waters. A limiting factor is a factor that restricts the size of a population from reaching its full potential. Kelp forests are most present in Southern California but can be seen most places along the California coastline. Because the sea otter only lives for around 10-20 years (Environment Canada, 2011), and is only able to produce one offspring every year, the population does not have the ability to grow quickly. Urchin barrens are disastrous to the environment as they result in an increase in carbon dioxide in the atmosphere and the likelihood of coastal erosion and storm surges. The tail comprises less than a third of the body length. As of 2006, the lingering oil in the area continued to affect the population of these valuable sea creatures. Biotic factors are the interactions between organisms. This challenge has affected even large estuaries such as the Elkhorn Slough Estuary located on Monterey Bay in Central California, US.

Marine Ecology is the scientific study of marine-life habitat, populations, and interactions among organisms and the surrounding environment including their abiotic (non-living physical and chemical factors that affect the ability of organisms to survive and reproduce) and biotic factors (living things or the materials that directly or indirectly affect an organism in its environment). For instance, turbidity is an abiotic factor that majorly affects the aquatic ecosystem. Abiotic factors are items that are not living (a = not, bio = life) chemical and physical attributes of an environment that affect living organisms and the function of the ecosystem. They both have multiple layers. Thirdly, sea otters expose themselves to diseases and pollutants through their feeding habits. Additionally, the damaging physical effects of oil contamination, as well as toxicological effects from ingestion and inhalation can lead to severe, long-term organ damage and other potentially life-threatening conditions. Some of the biotic factors include its predators and prey. By repeatedly foraging these contaminated prey, the otters put themselves at risk of harmful diseases.
