Dingoes are wild dogs that live in this area and will try to attack and eat the kangaroos.

Kangaroo Symbiosis

Respiration

-Uses less energy to breathe hopping then when their standing still

-They breathe in and out of their mouth and nose like humans do

-Their breathing is linked to their hopping

-When feet leave ground air is pushed out of lungs

-When feet touch the ground their lungs will refill

Circulatory

-They have a closed system

-There heart rate beats at about 40 bpm

-They are warm blooded

-Blood receives oxygen from lungs and transports it

-Arteries run away from the heart

-Veins run to the heart

Nutrition

-Eats flowers, ferns,moss,insects,grass and shrubs

-Kangaroos are herbivores

-They regurgitate their food

-Regurgitate means they rechew their food before they digest it

Digestion

-Stomachs are multichambered

-Food passes through compartments that are separated by muscle

-Middle of body acts as a fementation system

-Stomachs are large and chambered with long intestines

-Long intestines allows time for full absorption of nutrients

Food Getting

-They hop around to get their food

-They have very strong hind legs

-Their legs help them to hop in order to get food

Body Support

-Have large back legs for jumping

-Have long, thick, and muscular tail to help with balance

-Ears have the ability to rotate

-Have five digits on front limbs that helps them grab objects easier

Protection

-Box with their front paws, but defend with kicks from their hind legs

-When danger comes they warn others by stomping the ground and or thumping the ground with their tail

Movement

-Move by hopping

-They hop with their hind legs

-Use tails to help balance

-They cant move backwards

Osmotic Regulation

-Can survive by only drinking water twice a week

-They have accuracy in utalizing water found in foilage

-In colder months they can survive only on vegetation

Excretion

-It excretes salt that is concentrated in the urine to decrease water lassage

-The waste in the urine can reuse substance and help conserve water

-Cloaca excretes feces and urine

-To eliminate waste the organism consumes water ti make the waste more soluble

Temp Regulation

-Kanagroos are 70 percent water

-They only sweat when moving

-They lick forearms to cool down for evaporation

-Go into smaller positions so less is heated by the sun

-Fur is used in colder months for insulation

-Warm blooded

-Hemothermic

Mating

-They reproduce sexually

-They use nose touching

-If one is smaller it will hold its body closer to the ground

-They also sniff each other noses for mating
