Abiotic and Biotic Relations Abiotic and Biotic Relations. The major abiotic factors that affect polar bears are the cold, snow and water. The extreme cold in the Arctic region that the polar bear inhabits means that it has adapted in several ways.The polar bears have grown long, thick fur and have a thick layer of blubber just under the skin.They also have small ears and tails, which reduces the loss of cold through these areas.he extreme cold in the Arctic region that the polar bear inhabits means that it has adapted in several ways. The polar bears have grown long, thick fur and have a thick layer of blubber just under the skin.

Polar Bear A symbol of the Arctic, polar bears are the world’s largest land predator and biggest member of the bear family. With heavy fur, blubber up to four inches thick and black skin that absorbs heat from the sun, polar bears are amazingly well adapted to the Arctic climate. symbol of the Arctic, polar bears are the world’s largest land predator and biggest member of the bear family.

- Abiotic Factors:: are non-living physical and chemical elements of an environment. These factors are important for the survival of the organisms of that environment. For example, this black smoker (deep sea vent) is made of sulfide mounds, one abiotic factor of the environment.

- General Description: Polar bears are large bears. They have strong legs with large, flattened feet with some webbing between their toes that help with walking on ice and swimming. The wide paws prevent sea ice from breaking by distributing weight while walking.

Check my answer plz 1. Which of the following are biotic factors and which are abiotic factors? Rain and grass are biotic; wind and humidity are abiotic. Algae and fungi are biotic; temperature and rainfall are abiotic. Oxygen and sunlight are biotic; maple trees and spiders are abiotic. Fish and whales are biotic; plankton and bacteria are abiotic. 2. Why is it useful for an ecologist to identify the keystone species in an ecosystem? The keystone species is only important in early stages of succession, and so the ecologist can safely ignore changes in its population at later stages. The keystone species is the most susceptible to pollution, and so its numbers give an indication of the levels of pollutants in an area. The keystone species is critical to maintaining the stability of an ecosystem, and changes in its population indicate changes in ecosystem health. The keystone species is important for the cycling of matter and must be maintained or the biogeochemical cycles will be affected. 3. Competition over resources occurs between organisms participating in an herbivorous relationship. forming a symbiotic relationship. attempting to occupy the same niche. initiating primary succession after a disturbance. 4. The lowest trophic level in an ecosystem has the lowest quantity of stored energy. has the greatest biomass. is made up of heterotrophs contains detritovores. 5. What is true of the energy that is passed from one trophic level to the next in a food chain? About 10% of the energy passed from one level to the next is released as heat. About 10% of the stored energy of one level becomes stored energy at the next higher level. The energy at each level increases by about 10% with each move up in trophic level. The total energy at all trophic levels is constant, but only about 10% is available for use by organisms for life functions. 6. Autotroph is to producer as heterotroph is herbivore. consumer. decomposer. carnivore. 7. Which of the following is true of population cycles? Population cycles signal an imbalance in an ecosystem. Keystone species are necessary to establish population cycles. A new species introduced to an ecosystem tends to stabilize population cycles in the ecosystem. Population cycling helps maintain a healthy ecosystem. 8. An example of a pioneer species is a sparrow. a lichen. an earthworm. a spider. 9. Why are human disturbances often of more concern than natural disturbances? Human disturbances last much longer than natural disturbances so that a damaged ecosystem may have little or no chance of recovery. Human disturbances are stronger than natural disturbances and so the recovery needed is much greater. Human disturbances often cover much wider areas than natural disturbances, which means that more ecosystems are affected. Human disturbances affect all types of ecosystems, whereas natural disturbances are limited to certain types of ecosystems. 10. Suppose a particular community is concerned about a fox population that kills and eats chickens on the local farms. What is the best course of action by this community? Kill the foxes. Trap and transport the foxes out of the region. Introduce rabbits as an alternative source of food for the foxes. Build enclosures for the chickens that the foxes cannot access. Rain and grass are biotic; wind and humidity are abiotic. Algae and fungi are biotic; temperature and rainfall are abiotic. Oxygen and sunlight are biotic; maple trees and spiders are abiotic. Fish and whales are biotic; plankton and bacteria are abiotic. 2. Why is it useful for an ecologist to identify the keystone species in an ecosystem? The keystone species is only important in early stages of succession, and so the ecologist can. safely ignore changes in its population at later stages.

- Question:compare and give several examples of biotic and abiotic factors in a forest ecosystem. Answers:In a forest, abiotic factors include the non-living factors of lighting, water flow (rivers,lakes), amount of shelter (caves, roosts), and temperature.

Polar Bears polar bears are considered to be marine mammals. 1  A polar bear's front paws propel them through the water dog-paddle style. The hind feet and legs are held flat and are used as rudders. 2  A thick layer of fat, up to 11 cm (4.3 in.) thick, keeps the polar bear warm while swimming in cold water. Polar bears can obtain a swimming speed of 10 kph (6.2 mph). A polar bear's nostrils close when under water. Diving. Polar bears make shallow dives when stalking prey, navigating ice floes, or searching for kelp.

Biotic and abiotic factors in taiga assignment - black... Unformatted text preview: black spruce, Siberian spruce, and the jack pine are all biotic factors. They are living and grow in the environment. The animals such as the red fox, wolf, and bobcat are also biotic factors. They need to live in the wild and need food to survive. Some of the abiot-ic factors in the taiga is the soil, climate, water, air, temperature, and the sunlight. All of these factors are not living, but there could be living organisms that live inside these factors; such as small bugs and bacteria that live in the soil, or the fish that live in the wa-ter.

Abiotic and Biotic factors of a river/lake ecosystem? Temperature, light and wind turbulence are other abiotic factors but they are independent of the size of the drainage system since they can affect a larger region. Biotic factors are the organisms living in the system and their interactions.Many interactions between the abiotic environment are a result of the organisms living processes. Snails can only live in pond where calcium leaches into the water from the bedrock so the abiotic limits where snails can live.est Answer: The abiotic factors do include acidity, turbidity (clarity), nitrogen nutrient concentrations plus dissolved oxygen concentration. These are affected by the catchment or volume of the pond or lake.

- Polar bears are the primary predator in the marine ecosystem of the Arctic. They mainly hunt seals and the occasional young walrus or whale. In times of scarcity, they eat anything available, including fish, reindeer, birds, rodents, eggs, kelp, berries and even garbage. Jupiterimages/Photos.com/Getty Images.

Polar Bears The skin of the polar bear is black, something that is not easy to see. Its white fur actually allows light to reach this skin and the dark skin absorbs the heat from the sun, another adaptation of the polar bear to living in the extreme cold of the Arctic.

- The polar bear's Latin name, Ursus maritimus, or sea bear, refers to the animal's close association with the Arctic's chilly waters and its sea ice. The polar bear is the only bear considered a marine mammal by most countries within its range (Canada classifies them as terrestrial mammals). The polar bear's life cycle is closely tied to the sea ice. Polar bears rely on the ice to travel, hunt seals, breed, and in some cases to den.
