A consumer is someone who buys things like goods and services. For example, you yourself are a consumer because you buy goods like groceries from Walmart or wherever you shop. Basically, anyone can be a consumer because you always buy things from the grocery store or get service done like your nails or a car wash.
okay so the word consumer actually has diff meanings and i'll list both of them out to you, just choose the one that best fits whatever you're working on:
A person who purchases goods and services for personal use.
ex: An example of a consumer is a person who purchases a new television
A person or thing that eats or uses something.
ex: Carnivores that feed on herbivores or detritivores are called secondary consumers
This is written in a passive voice and needs to be rewritten in an active voice and reduce length. After 12 weeks had passed, each mouse was randomly placed in one of two treatment groups; in all cases, a die was rolled (was rolled is a passive voice right now) by an experimenter for each mouse, and if it landed on an even number, the mouse was placed in the group that received a pill.
