Well, some simple abiotic factors would be that giraffer's are affected by the pH of the water they drink, its salinity, body temperature, environmental temperature, as well as air qualities. I could look into the actual environmentalcontext fo the giraffe species and see what it lives around.\n\nfor biotic factors, we could say human encroachment, predation of lions, for instance. We also know that the leaves and grasses it feeds on is another biotic factor. We can look at sexual competition (if there is any) in the giraffe species, and of course any incidences of bacterial disease that a giraffe is significantly prone to.

Animals take in Oxygen and give off Carbon Dioxide.\n\nPlants do the opposite.

come on peace that is not the answer.\nGiraffe are the tallest animals in the world. Males can reach as high as 6 meters (19 feet) tall and female giraffe can measure up to5 meters -17 feet) tall. Their neck accounts for the added height and is by itself approximately 2.4 meters (8 feet) in length and can weigh almost 227 kilograms (500 pounds). \n\nFUNNY THIGS :\ntallest man in the world reaches his belley.\nhe needs telescope to see his leg.\nand most of all, \ndamm...he is taller than me.\ni cant belive it.

Most lizards are green, probably for camouflage.\n\nSince dinosaurs are lizard-like, they are expected to be green.\n\nHowever, dinosaurs are expected to be a variety of colors, green does not have much of an advantage. Lizards, though primarily green, can have a variety of colors or be able to change colors.\n\nAlso, it's easier to imagine a green dinosaur then a bright pink dinosaur. :D

You mean Yoshi, as in the dinosaur friend of Mario? Only the green variant of Yoshi has these colored boots.\n\nIn this case, it provides a color contrast to his green skin. See, when a character is designed, the designers consider the art aspects as well as the marketability aspects. Contrasting colors, such as red and green, usually make for a more interesting design.\n\nIn the event of the video game world, all yoshis are born with shoes. Green yoshis are born with red shoes. How they are born with shoes in the first place is a physical phenomenon exclusive to the Mushroom Kingdom.

Lions do not attack giraffes - there is too much risk to injury created from kicking etc. How would the lioness' bring down such a tall and heavy animal, when it cant even reach the tracheae or rump? The greatest risk faced by giraffes due to their morphology, is whilst giving birth and drinking. Firstly, because they are unable to keep watch as effectively (and many females move away from the herd whilst giving birth). Predators and scavengers make opportunity of newborns, so there is great risk to losing any offspring. When at a watering hole, they are susceptable - as are most animals - to crocodile attacks and because they have to splay their legs are not in a great position to flee increases risk.

Green grapes are the only ones in my world.\n\nI was amazed by all the people who answered purple, I thought green grapes were more common.

in the case of giraffes and okapi, they have very long, nearly prehensile tongues used to strip leaves and branches from trees.  the dark colour is due to higher levels of melanin in the tongues.  granules of melanin in the integument of the tongue help to strengthen and protect the tongue from mechanical injury to some degree, but their primary 'purpose' is to protect the tongue from sunburn.\n\nas you can imagine, a giraffe's tongue gets quite a bit of exposure to harsh African sunshine.  now imagine getting a sunburn on your tongue.  ouch.\n\nin the case of chows, the colour may have been bred into the dogs for some reason (i.e. aesthetics) by the breeders, or more likely, the genes for that colour were linked to another trait that the breeders desired.\n\ni'm not aware of bears having black tongues.  which species is that?

it has to do with wavelength of the light.  the reason why plants are green is because they don't absorb the green light, green litht has a shorter wavelenght.  on the other hand If the object absorbs  blue, green and yellow light it will appear red  so I guess it does have to do with the material\nhope it helps

Giraffes vocalize at an infrasound level - sound at a frequency too low to be heard by a human ear.

Yes and yes. They are responding to the motion of the cape, not the color.\nTests for this sort of thing are pretty cool and pretty cruel. They train a bull to get food from a square red box. The bull associates food and the square red box. Then they put two boxes out there - a square red box with food, and a square green box with a nasty surprise (frequently noise or a squirt of water that the bull hates) - and see if the bull can find the food more often than random chance would account for.\nAnd they can't.
