It had long legs and it a wide skull with lots of power in its bite. Albertosaurus is considered by many scientists to be the best known of the tyrannosaurs. A number of nearly complete skeletons, two adults and a juvenile, have been found. There are two recognized species and several in dispute. It is sometimes referenced as a transitory animal, a creature on its way to evolving into T. rex, but it appears that it was extremely successful and longer lived than the Tyrannosaurus
For instance, a certain kind of insect may be introduced to a new place in order to kill a different kind of insect. This can balance the other insect's population or this can eventually cause the other insect to become extinct. The new insect may kill off the other insect by taking over their niche.

Maria Call Professor Williams English 100 7 March 2013 Atrazine in Water is a Threat Dirty water is one of the world’s biggest health risks and continues to threaten quality of life. We rely on clean water to survive and key sources that we receive our water from are being tainted with a chemical called atrazine, which is an economical pesticide used on most corn, grain, sugar cane, citrus, pineapple, and sorghum to control weeds (Williams 23). Atrazine is also one of the most widely used pesticides in the world and in the United States alone, more than 80 million pounds are applied annually (Hayes et al. 1). Hayes argued, “the impacts of atrazine on amphibians and on wildlife in general are potentially devastating” (Hayes et al.
People are not usually threatened by spiders. About 15 species are dangerous, but bites that end in death are not common. The silk that the black widow spider spins for its web is very strong.

It has several teeth but only the back two can inject venom, which is used to subdue and kill prey but is not considered to be dangerous to an adult human.
This reflects the fact that amphibians are a large part of their diet. Garter snakes, like all snakes, are carnivorous. Their diets consist of almost any creature they are capable of overpowering: slugs, earthworms, leeches, lizards, amphibians, ants, crickets, frog eggs, toads, minnows, and rodents. When living near water, they will eat other aquatic animals. The ribbon snake (Thamnophis sauritus) in particular favors frogs (including tadpoles), readily eating them despite their strong chemical defenses.
