Study Guide

Decomposers

Decomposers (saprotrophs) are organisms such as bacteria and fungi that break down the organic matter in the dead bodies of plants and animals into simple nutrients.

Liver

The liver produces bile which emulsifies (separates) fat.

Moon

Tides are caused by the gravitational interaction of Earth and the Moon.

Stomach

Food is mixed with gastric acid and pepsin in the stomach to help break down protein.

Vectors

Velocity and displacement are vector quantities which means each is fully described by both a magnitude and a direction. In contrast, scalar quantities are quantities that are fully described by a magnitude only. A variable indicating a vector quantity will often be shown with an arrow symbol: \(\vec{v}\)
