An investment involves buying a valuable commodity and keeping it for a longer period without selling to make better profits and the more you keep adding the the commodity you bought the more profits you stand to get in the future and it's quite different from a business.
A business involves selling of goods or rendering services to make money either daily, weekly or even monthly and just like someone in this thread @Barikui1 specified, one can survive on business, basically from the excess profits made but that can't be done in an investment, for instance if you buy Bitcoin or shares from a company you'll have to wait for a longer period to get better profits.

ifof this element narrow down to profit making most time some business can yield profit than some investment all depends on what one invested and the business one is also engaged on.
