For example the sea otter has a very low biotic potential. 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). 3 = 34. 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.

Abiotic factors are non-living variables. Both affect diversity and distribution. However, countries around the globe have enacted legislation outlawing their hunting. The Kelp forest is much like a forest on land. Sea urchin persistence was also related to the coast-ocean gradient. We reasoned that energy requirements, which differ over the year in accordance with the life history of the snake, would affect hunting strategy. ...

A keystone species is one that exerts a large, stabilizing influence throughout an ecological community. Weather patterns are influenced by climatic phenomena such as the North Atlantic Oscillation (NAO). Another reason that sea otters are susceptible to oil spills is because they often travel in large same-sex rafts (Environment Canada, 2011). In 2006, a law was passed to place a maximum fine of 25,000 for dumping the feces. ... Common invertebrates found are bristle worms, scud, prawn, snails, jellyfish, crabs and sea stars.

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. Crude oil normally penetrates the fur of the otter destroying the air layer that is trapped next to its skin. Kelp forests are most present in Southern California but can be seen most places along the California coastline. Urchins move in "herds," and enough urchins may remain in the "barrens" of a former kelp forest to negate any attempt at regrowth. More kelp forests result in fewer urchin barrens, as well as an increase in the absorption of carbon dioxide from the atmosphere through photosynthesis and release oxygen back into the air.
