WHAT DO I EAT? The prickly pear, like most other plants, eats through photosynthesis and drinks water. However, because the prickly pear is a desert plant it has adapted to the dry soil of the desert, and does not need much water to keep it satisfied.

A measuring cup can be used to measure volumes of liquids. This cup measures volume in units of cups, fluid ounces, and milliliters. Volume is the quantity of three-dimensional space enclosed by some closed boundary, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic meter.
Thus, a weightless object in outer space has the same mass as it has on earth. Units of Volume. The liter (L) is the basic unit of volume. A typical thermos bottle holds about 1 liter; a standard flush toilet flushes about 20 liters of water. Units of volume are cubed (i.e., three-dimensional) units of length.
