An example of a limiting factor is sunlight in the rainforest, where growth is limited to all plants in the understory unless more light becomes available. To achieve this, the sea otters that are carnivorous feed on various marine species such as crabs, clams, urchins, snails, and worms. Biotic factors include disease, predation, cannibalization, and nutritional requirements that may be influenced by the quantity and quality of added food, organic matter, bacteria, algae, and/or organisms such as meiofauna in the sediments. Both affect diversity and distribution. The largest and most effective although is food limitation. Other than special interactions, there are other factors that limit the sea otters population. Sea otters reside in the underwater which has extremely cold temperatures. 3 = 102 would be used to verify the equation 102 ? Scud Sea Otter. The spatial distribution of kelp (Laminaria hyperborea) and sea urchins (Strongylocentrotus droebachiensis) in the NE Atlantic are highly related to physical factors and to temporal changes in temperature. Weegy: 34 x 3 = 102 would be used to verify the equation 102 / 3 = 34. Other factors include geographical space, predation, climate, competition (for prey, food, mates) etc. Studies show that the presence of otters increased the carbon storage of kelp forests from 4.4 to 8.7 megatons. The amount of food & water in a habitat is an example of a limiting factor. The sand or dirt on the bottom of the sea is an abiotic factor because it is nonliving. Other factors include geographical space, predation, climate, competition (for prey, food, mates) etc. In a food we a sea otter is a second level consumer because it is a predator and prey. The Pacific Ocean biome contains many different types of living organisms, which all rely on different things in order to survive, but what all of the animals have in common is they can be described as either an autotroph, ... A keystone species of the Pacific Ocean is the sea otter species. ABIOTIC FACTORS Also with out sunlight then the sea otters won't have any food. In the recent past, sea otters nearly became extinct due to large-scale commercial hunting for its pelt. ... WINDOWPANE is the live-streaming social network that turns your phone into a live broadcast camera for streaming to friends, family, followers, or everyone. Sea otters feed on a large number of crabs to retain their body weight. Sea otter numbers have declined in southwestern Alaska over the past 20 years. On land, the otters face threats from bears and coyotes. What Is The Importance Of Insects In The Ecosystem? 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. Abiotic factors are the nonliving elements, like air, water, soil and temperature. Urchins move in "herds," and enough urchins may remain in the "barrens" of a former kelp forest to negate any attempt at regrowth. ]. Cyanobacteria produce _______ from nitrogen gas as part of the ... Divide 7/15 by 3/5. ... Because sea otters live very close to land, any pollution running off to the ocean will definitely affect them. They both have multiple layers. They are adapted to this kind of environment by possessing a dense fur coat which insulates the body from cold. As top predators, sea otters are critical to maintaining the balance of nearshore ecosystems, such as kelp forests, embayments and estuaries. They provide crucial habitat and food for other marine organisms and also help to contain coastal erosion. User: whats the sum of 3/8 and 1/16 Weegy: 2 + 2 = 4. Biotic factors are the living are organisms within the particular Biome. [ If they don't have any space then they won't have anywhere to reproduce. Sea Urchin Grey Whale. BIOTIC FACTORS However, countries around the globe have enacted legislation outlawing their hunting. and are the smallest marine mammal in North America.
