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 defend themselves from predators by hissing, striking, making a striking pose shaped like an S, biting, and flying.
Monarchs have many natural enemiesâpredators, parasitoids, and parasites can harm monarch eggs, larvae, pupae, and adults.Predators such as spiders and ants attack eggs and young larvae feeding on milkweed, whereas birds and wasps can prey on adult monarch butterflies.Parasitoids are specialized insects such as small flies and wasps that lay eggs on or inside other insects.onarchs have many natural enemiesâpredators, parasitoids, and parasites can harm monarch eggs, larvae, pupae, and adults.
