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.
In metric system, the base unit of volume was litre (american spelling is liter) and accepted in SI (International system of units) although it's a non SI unit. The base unit of volume in SI is cubic metre (meter). Although many volume units are the same in imperial and US customary system (cubic inch, cubic feet etc), several customary units are grouped into two categories to measure liquid and dry volume capacities separately but in imperial system there is only one category.
