Respiration

You may have heard of photosynthesis. That's where a plant uses energy from the Sun's rays to make its own food.

The opposite of photosynthesis is called respiration. The difference is that respiration happens in all organisms, including animals, plants, and bacteria.

During respiration, energy is made to support life. Without it, humans, other animals, plants and even bacteria wouldn't exist!
