a small member of a lerge group that includes spiders, scorpions, mites, ticks and daddylonglegs. An arcahnid is closely allied to the insects, but breathes no air by means of tracheal tubes or pulmonary sacs and has four pairs of walking legs, no antennae, and no wings. The body is divided into only two regions.
a person who studies
living organisms and their relationship to one another.
a natural community of plants and animals, its composition being largely controlled by climatic conditions.
an animal that has wings, feathers, two legs, and a beak or bill. Birds have backbones, are warm-blooded, and lay eggs. Birds can fly except for a few e.g. an ostrich

the arrangement of food, water, shelter, and space necessary for a species' survival.
any one animal that feed on grass or other plants. The ungulates are herbivores.
The act or state of hibernating. It is a state of death-like sleep, where-in the animal's breath and pulse almost stop and its temperature drops to a point very little above that of its environment.

a living body having organs that work together to carry on the processes of life; individual animal or plant.
an animal or plant that lives on or in another from which it gets food, always at the expense of the host.

their habitat.
a wildlife management technique used to place species back into
an area where they had disappeared or become dangerously low in numbers.
any one of a class of cold-blooded animals with a backbone which breathe by means of lungs and usually have skin covered with horny scales. Reptiles creep and crawl, they include crocodiles, alligators, lizards and snakes.
an animal that feeds on decaying matter. Vultures, jackals and some snails and beetles are scavengers.
<P>Species:

living on the ground, not in the air, water or trees.
a species likely to become endangered if it is not protected.
the process of making or becoming urban.
