These filter feeders indiscriminately sieve particles out of the water resulting in them accumulating high concentrations of pollutants and disease pathogens. This caused a huge downfall of the sea otters population, which only got worse. 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. Sea otters live in communities with many other species including sea urchins, orcas, starfish, and many types of fish. People affect sea otter populations through direct shootings and trapping sea otters in fishing nets. LOGIN TO VIEW ANSWER. ... Sea Otters: The haviest member of the weasel family, the sea otter is also the second smallest marine mammel. 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. Sea urchin persistence was also related to the coast-ocean gradient. Biotic factors are the interactions between organisms. Also with out sunlight then the sea otters won't have any food. Such an increase is a result of the food web that forms within this ecosystem formed by the sea otters, crabs, and sea slugs.
