[MCU]Why does Venom need a person to act as a host?

I understand he’s a symbiote but, it appears in the trailer that he really shouldn’t need a host to structure off of. Could venom be effective independent of a host body?

The symbiote doesn’t need a host to provide structure, it gets nutrients/energy/food from the host. There are chemicals produced by the brain that the symbiote need in order to function/survive, hence them finding hosts.

And as has been said before, Venom is not part of the MCU.
