What Is A Producer?

There are two types of producers.  One is found in social studies and the other one in science.  In social studies a producer is any person or company that makes items that are sold to consumers (buyers).  In science a producer is any thing that makes something used by something else in our world.  An example of each would be:
Social Studies - a company that makes cars is a producer
Science -  when chemicals are mixed they give off a gas  (they are called producers because they produce the gas).
