Factors of its environment) The type and extent of the sea ice are the main factors that determine the quality of the polar bear habitat.

Structural adaptations) A white appearance, thick layers of fats and fur, a greasy coat that sheds water after swimming.

Behavioural adaptations) Hibernation habits, aggressive behaviours and communication efforts.

Factors of environment: Abundance of food, a lot of water, trees for nesting and perching.

Structural adaptations: hollow bones to make it easier to fly, sharp beak to catch fishes in the water

Behavioural adaptations: They vigorously defend their nesting territory when breeding, most of the bald eagles migrate during winter.

Factors of its environment:Snow,Cold,Freezing,lots of light,Not much wind

Structural Adaptations:Broad feet to walk on the snow easily,sharp claws to grip prey,sharp teeth to rip prey meat and chew it and small ears to lose heat slower to the cooler environment

Behavioural Adaptations:Swimming in water to ambush prey and they hibernate to get through months when food is scarce.

Factors of the environment:Abundance of Fish and marine mammals.Temparate and subtropical waters.

Structural adaptation Shark blood has a high hemoboglin concentration. Sharks also have a torpedo shaped body to water resistance, they also have stiffer tail fins and more symmetrical bodies.

Behavioural Adaptations: Great white Sharks hunt during the night between low and high tide typically in shallow water near reefs. Great white sharks also ambush their prey from the bottom

Factors of the environment:

Water plants,animals,mircrobes,temperature between 12and24 degrees

Structural adaptation :

-shark bodies have a torpedo shape to reduce drag in water

-good eyesight to spot preys and predators

-streamline body to swim faster away from predators

-sharp teeth to feed on preys

Behavioural adaptation :

-Incredibly curious

-they will often approach the surface of water, sticking their head out to take a look in an action known as spy hopping

-average length 5.3 metres long

Factors of environment:

Abundance of food- other fishes in the sea,reptiles, other birds

Availability of sunlight- A lot of sunlight available

Temperature- average of 35 degrees celsius

Availability of water- A lot of water available

Prey- Fish as their primary food source, sea birds, ducks

Predators- No natural predators, us humans are their biggest enemy

Structural adaptations- sharp,pointed beaks to rip and tear their prey into bite-sized pieces

have powerful legs and feet that have large talons used to kill their prey

Behavioural adaptations- build nests very high up in trees so that predators cannot harm their young

During frigid periods when food is scarce they hibernate so that during day they save energy.

-Yu Yang.

Factors of its environment:

Temperature: 12 - 24

Amount of dissolved oxygen in water: 1.7ml - 2.9ml

Food: marine mammals (eg. seals and sea lions) Fish (eg. tuna and other large species)

Presence of predators/other organisms: They may face threats from larger sharks such as orca and occasionally from humans.

Structural adaptions:

• Streamline body - reduces water resistance to move faster so as to catch prey more easily.

• Muscular tail - provide propulsion during swimming and allows them to reach high speeds while persuading prey.

Behavioural adaptations:

• Shark migrate for feeding and mating as well as to avoid competition and exploit favourable environments

Factors of its environment: A lot of atmospheric air, there is availability of food as there are fish in the bodies of water and surrounding temperature in the habitat is high allowing the bald eagle to maintain a normal body temperature. There are not many predators as the bald eagle is one of the top predators.

Structural adaptations: They have sharp pointed beaks designed for tearing and ripping its prey onto bite sized pieces.

Behavioural adaptations: Vigorously defends their nesting territory, and gregarious when not breeding.
