* Oxygen: During photosynthesis, plants take in carbon dioxide and water, and using sunlight as energy, they release oxygen as a byproduct. This oxygen is what animals breathe to survive.
* Food: Plants produce sugars (glucose) through photosynthesis. These sugars serve as their energy source and are also stored within the plant. Animals eat plants, consuming these sugars and converting them into their own energy.
So, photosynthesis is crucial for the entire food chain, providing the oxygen and energy necessary for life on Earth.
