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.
Benefits of Growth. Even adult black rat snakes are consumed by a variety of predators; red-tailed hawks (Buteo jamaicensis), red-shouldered hawks (Buteo lineatus) and eastern king snakes (Lampropeltis getula getula), will consume black rat snakes. Because of this, snakes who grow and attain large sizes quickly are more likely to survive. This was demonstrated in a study by Gabriel Blouin-Devers et al. that showed mortality in black rat snakes is highest for hatchlings, steadily dropping with increasing size.
