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.
Any unit of length gives a corresponding unit of volume, namely the volume of a cube whose side has the given length. For example, a cubic centimetre (cm 3) would be the volume of a cube whose sides are one centimetre (1 cm) in length.n the International System of Units (SI), the standard unit of volume is the cubic metre (m 3). The metric system also includes the litre (L) as a unit of volume, where one litre is the volume of a 10-centimetre cube.
