Gizzard
Birds such as chicken, doves and others, and earthworms have gizzard which are responsible for storing and softening the consumed food in their digestive tract. The gizzard serves as the grinder of these food in preparation of the absorptive phase of the G.I tract.
A plant, Reason why is because since a plant is a producer it’s able to use energy from the sun to produce its food from carbon dioxide and water,,,((Might not make much sense but a plant is an organism))
