Plants are fixed to the ground with the help of roots. The roots absorb all the essential nutrients from soil along with water. Later it is used for producing food in plants.
Animals cannot prepare food of their own. They depend on plants or other animals for food. They move around in search for food and also for protecting themselves.
Oxygen is the gas that is involved in respiration for both plants and animals. Both plants and animals are made up of cells.
