Another limiting factor came into place when there was an oil spill in 1989, killing approximately 5000 Sea Otters. Other than special interactions, there are other factors that limit the sea otters population. To achieve this, the sea otters that are carnivorous feed on various marine species such as crabs, clams, urchins, snails, and worms. Weegy: 34 ? Biotic factor are the living organisms and their actions and biproducts that contribute to the environment. Weather (short-term variation in meteorological conditions) can cause variations in parasite distributions whilst synchronously influencing host abundance but will affect specific host-parasite interactions differently, –. As top predators, sea otters are critical to maintaining the balance of nearshore ecosystems, such as kelp forests, embayments and estuaries. [ If they don't have any space then they won't have anywhere to reproduce. Population.

Sea otters are a keystone species, meaning their role in their environment has a greater effect than other species. 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. Biotic Factors.

Seagrass meadows are significant to the ecosystem as they result in the protection of the coastal regions and preservation of the habitat for fish. Biotic factors are all the living elements of the ecosystem, including the plants, animals, fungi, protists and bacteria. Kelp forests are most present in Southern California but can be seen most places along the California coastline. Places such as British Columbia, Aleutian Islands, and the Big Sur coast of California have had major improvements in the health of their coastal ecosystems due to the re-introduction of otters. 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).
