What are the three kinds of consumers?

Answer 1

I like this question! There are more than three actually. We have 1. Those who eat, such as those who consume veggies, meat, potatoes (these eventually consume a lot of space). 2. Those who buy, those who purchase goods and services (hardware, cars, haircuts, entertainment etc.) 3. Those beings or things that simply consume energy, like black holes, automobiles (which is kind of like "eating" hydrocarbons. But I must mention number 4, and that is the reader like you who loves to consume knowledge.
