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. Photosynthesis occurs when plants take light energy and converts it into chemical energy.
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.
The basic unit of volume in the metric system is a cube, 10 centimeters on each side. Contained in this cube are 1,000 cubic centimeters or one liter. A liter contains slightly more liquid than a quart. Very large volumes may be measured in cubic meters (1 cubic meter = about 264 gallons).
