(a) solute = substance (solid or liquid) in lesser amount, which will [dis]solve into the solvent
(b) solvent = substance (liquid) in larger amount, which [dis]solves the solvent
it's dissolvability is called "solvency"
water is known as the universal solvent because it is abundant on Earth and has a high solvency
(c) solution = the combination of solvent + solute
depending on the saturation of solute within solvent, the solution may appear clear, like the solvent
**think of warm sugar-water (solution), when all the sugar (solute) dissolves into the water (solvent), the solute seems to have disappeared
None of the above because they are non pollutant
Answer:
organisms that can't make their own food are known as heterotrophs
