Hi!
The answer you're looking for is the Fungi Kingdom
This kingdom is composed of molds, yeasts, and mushrooms. These organisms don't move nor contain chlorophyll and therefore cannot make their own food. The technical name for this kind of organism is heterotrophs. They have to eat organic carbon instead of fixing it from inorganic sources. They can be parasites (harming the host) or symbionts (mutual benefit) of animal, plants or other fungi.
