[Photosynthesis] 3.What is the process of plants consuming the food ? How is it consumed ?

All living things comsume food . Plants do not move,how do they consume their food?

The process of using food and oxygen to get energy is called respiration. Plants must use the energy they trap in the food to stay alive. That's where respiration comes in. At night, plants take in oxygen and use it to get energy from the food they stored. This is a chemical reaction. This is the same reaction that takes place in animals that eat the plants.

Respiration is essential to provide metabolic energy and carbon skeletons for growth and maintenance. As such, respiration is an essential component of a plant€s carbon budget.
