Biotic factors are extremely important to an ecosystem. 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. People affect sea otter populations through direct shootings and trapping sea otters in fishing nets. 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. 3 = 102 would be used to verify the equation 102 ? There are many biotic factors that contribute to the ocean biome. Sea otters reside in the underwater which has extremely cold temperatures. Biotic Factors of the intertidal zone. Eventually, the seagrasses become clean and healthy resulting in higher populations. The high metabolism comes from the food eaten by the sea otters. First, one of the biggest threats to the existence of sea otters is humans. In the recent past, sea otters nearly became extinct due to large-scale commercial hunting for its pelt. Some of the biotic factors include its predators and prey. They provide crucial habitat and food for other marine organisms and also help to contain coastal erosion. The kelp forests in California are one of the most abundant ecosystems in the world. 2.
