Diode rectifier characteristic. In the reverse direction, the diode rectifier will ultimately break down. The breakdown voltage is normally well in excess of the turn on voltage-the scales on the diagram have been altered (compressed) in the reverse direction to illustrate that reverse breakdown occurs.
Common kingsnakes are beneficial for the ecosystem. As predators, they help keep numbers of rodents, frogs and other snakes like rattlesnakes and cottonmouths in check. They are eaten by larger snakes and predatory birds and mammals. They also get some parasites from the group apicomplexans.ommon kingsnakes are eaten by alligators in Florida, larger snakes, hawks, raccoons, striped skunks, and Virginia opossums. They defend themselves from predators by hissing, striking, making a striking pose shaped like an S, biting, and flying.
Of these, 375 are venomous. Snakes consume a variety of items including termites, rodents, birds, frogs, small deer and other reptiles. Snakes eat their prey whole and are able to consume prey three times larger than the diameter of their head because their lower jaw can separate from the upper jaw. To keep prey from escaping, snakes have rear-facing teeth that hold their prey in their mouths. Venomous snakes inject their prey with venom, while constrictors squeeze their prey. They do not need to hunt everyday. Anacondas and pythons can survive for up to a year without food after feeding.
