Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. Also, as lichens die, they provide some organic matter that also contributes to soil.

The hamstrings are made up of three muscles: the biceps femoris, semitendinosus and semimembranous. In addition, the tendons are located at the back of the thigh and cross the hip and knee joints. As the hamstrings cross two joints, they have two actions, including knee flexion and hip extension, as well as hyperextension.
