Other factors include geographical space, predation, climate, competition (for prey, food, mates) etc. The interrelated abiotic and biotic factors in an ecosystem combine to form a biome. Another reason that sea otters are susceptible to oil spills is because they often travel in large same-sex rafts (Environment Canada, 2011). However, countries around the globe have enacted legislation outlawing their hunting. The River to sea preserve is full of organisms, there are different abiotic and biotic factors of the ecosystem that affect each other. Among the widespread species of seagrasses is the Zostera, also known as the eelgrass that has been on the decline in the recent past due to the large population of crabs that have been feeding on them. They have thick fur that generates heat to keep their bodies warm. Share what’s outside your window and all around you.

A sea otter pup trapped in a single use plastic bag ! What are the abiotic factors & biotic factors of sea otters? Since they have to consume at least 25% of their body weight each day to stay alive, sea otters prey on filter feeders such as mussels and clams. This challenge has affected even large estuaries such as the Elkhorn Slough Estuary located on Monterey Bay in Central California, US. Sea urchin persistence was also related to the coast-ocean gradient. 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). Biotic Factors of the intertidal zone. Sea otters reside in the underwater which has extremely cold temperatures. The specific role of the sea otters in the eco-system is as follows; ‘’Kelps’’ are brown algae seaweeds growing rapidly underwater covering 25% of the world’s coastlines. Both abiotic and biotic factors determine both where an organism can live and how much a population can grow. The high metabolism comes from the food eaten by the sea otters. Sea turtles for example is an organism in the River to sea preservation. Consequently, the sea otters … In addition, genetic variation is also possible due environmental conditions the vector is exposed to As a matter of fact, the Abiotic and biotic factors determine the survival of the parasite and studies are needed to determine their effect on B. pfeifferi and hence S. mansoni population.

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, –. Related Questions in Biology. We questioned to what extent active hunting is used by Cerastes vipera and whether there are biotic and abiotic factors that affect the hunting strategy. On a large scale, we identified borders for kelp recovery and sea urchin persistence along the north-south gradient. The largest and most effective although is food limitation. These lifeforms rely on abiotic factors as they directly affect their growth, survival and reproduction. ... Common invertebrates found are bristle worms, scud, prawn, snails, jellyfish, crabs and sea stars. To this day, sea otter trading/selling has become more rare. BIOTIC FACTORS Sea otters are a keystone species, meaning their role in their environment has a greater effect than other species. 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. Kelp forests are most present in Southern California but can be seen most places along the California coastline. Obviously, the rock would be an abiotic factor. The biotic factors would be the sea animal itself and the abiotic factor would be the sea, or the food, sunlight, every non living thing New questions in Biology Explain the differences between the structures of wind and insect pollinated plants and adjust the mark scheme. Biotic factors are the living are organisms within the particular Biome. Some of the biotic factors include its predators and prey. Biotic factor are the living organisms and their actions and biproducts that contribute to the environment. Thankfully, in 1911,sea otters received protection, as the International Fur Seal Treaty was established to prevent various exercies of trading. 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. As top predators, sea otters are critical to maintaining the balance of nearshore ecosystems, such as kelp forests, embayments and estuaries. Some of the biotic factors include its predators and prey. Some predators like the great white shark may kill the otters but not feed on them. What Is The Role Of Vultures In The Ecosystem And Wildlife Conservation? In 2006, a law was passed to place a maximum fine of 25,000 for dumping the feces. Scud Sea Otter. Sea Urchin Grey Whale. The tail comprises less than a third of the body length. Diseases and infections also caused a decrease in population specifically when pet owners started dumping cat feces down storm drains and toilets. Males weigh 22-45 kg and are 1.2-1.5 m in length. 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. For instance, turbidity is an abiotic factor that majorly affects the aquatic ecosystem. They provide crucial habitat and food for other marine organisms and also help to contain coastal erosion. Crude oil normally penetrates the fur of the otter destroying the air layer that is trapped next to its skin. 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. Sea Otters need sunlight and space to survive. We reasoned that energy requirements, which differ over the year in accordance with the life history of the snake, would affect hunting strategy. Jellyfish Crab. 7/25 C. 21/75 D. 75/21. Thus, the reduction in the numbers of the sea urchins, caused by the presence of sea otters, prevents the decimation of the kelp forests. Sea otters are a keystone species, meaning their role in their environment has a greater effect than other species. In a food we a sea otter is a second level consumer because it is a predator and prey. If one raft of 200 males were to be caught in an oil spill, this would greatly reduce the fertility of the sea otter population moving forward, and likely have significant population trauma many years into the future (Environment Canada, 2011). First, one of the biggest threats to the existence of sea otters is humans. Biotic resources include every lifeform in an ecosystem. Females are slightly smaller, weighing 14-33 kg and measuring 1-1.4 m in length.

This is an area of the sea without kelp forest cover. What are the abiotic factors & biotic factors of sea otters? Sea turtles are Biotic organisms because they are living. The shift in hunting strategy raises a number of questions concerning the ecological consequences of alternating these strategies (Wall et al., 2013) and the factors determining them. Weather patterns are influenced by climatic phenomena such as the North Atlantic Oscillation (NAO). 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. ... Because sea otters live very close to land, any pollution running off to the ocean will definitely affect them. Fourthly, sea otters are also threatened by predators that live underwater like orcas, sea lions, and bald eagles.

Another limiting factor came into place when there was an oil spill in 1989, killing approximately 5000 Sea Otters. Biotic factors are extremely important to an ecosystem. What are the abiotic factors of a sea otter habitat? Once containing more than half of the world’s sea otters, this population segment, which ranges from Kodiak Island through the western Aleutian Islands, has undergone an overall population decline of at least 55–67 percent since the mid-1980s. Also with out sunlight then the sea otters won't have any food. Consequently, the sea otters die from hypothermia. Biotic Factors Phytoplankton. The opposite of biotic is abiotic, which includes the physical and chemical factors present in the environment. Some of the abiotic factors are the water temperature, oxygen, and sunlight. By Sharon Omondi on December 12 2019 in Environment. In the recent past, sea otters nearly became extinct due to large-scale commercial hunting for its pelt. Biotic factors are all the living elements of the ecosystem, including the plants, animals, fungi, protists and bacteria. Studies show that the presence of otters increased the carbon storage of kelp forests from 4.4 to 8.7 megatons. ABIOTIC FACTORS Females are slightly smaller, weighing 14-33 kg and measuring 1-1.4m in length. Bristle Worm. A. Eventually, the seagrasses become clean and healthy resulting in higher populations. 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. List two examples of both biotic and abiotic factors for the sea otter population. A limiting factor is a factor that restricts the size of a population from reaching its full potential. High levels of turbidity inhibit the growth of submerged plants. A collection of kelps result in the formation of kelp forests. Urchins move in "herds," and enough urchins may remain in the "barrens" of a former kelp forest to negate any attempt at regrowth. 1. For example the sea otter has a very low biotic potential. 2. This answer has been confirmed as correct and helpful. 2. We questioned to what extent active hunting is used by Cerastes vipera and whether there are biotic and abiotic factors that affect the hunting strategy. The males are polygynous as they may take up multiple female partners. 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.
