Case Study: Levene
Not only bees pollinate flowers. Moths have a specialized mouth structure called a proboscis that is used to extract nectar and pollinate the flower. The moth benefits by getting food and the flower benefits by being pollinated.
Frogs eat insects, and frogs are in turn eaten by larger animals such as birds. Frogs hibernate, or more correctly, they estivate. During estivation, frogs lowers their body temperatures in cold weather and go into a kind of dormancy. Frogs can "migrate" in that they move across land to find ponds and water sources.
Williamsburg's jail, or gaol, set the standard for colonial prison architecture. Visit the building this year as we celebrate the 75th anniversary of its reconstruction. Architectural historian Carl Lounsbury describes the structure.Author(s):

Kinetic and potential energy of atoms result from the motion of electrons. When electrons are excited they move to a higher energy orbital farther away from the atom. The further the orbital is from the nucleus, the higher the potential energy of an electron at that energy level. When the electron returns to a low energy state, it releases the potential energy in the form of kinetic energy. (02:25)
The coyote has good senses of hearing, sight, and smell used to detect prey. After targeting the prey, the coyote uses its fast speed to capture and kill the animal.
Deer are herbivores, meaning they graze on plants. Deer are consumed by coyotes, which use their keen eyesight and speed to attack the deer.
