Biotic would mean living so fish and sea plants
I may not be able to make you a presentation, but I can help you on the idea behind it. Photosynthesis is 6 Carbon dioxide 6 water and light to make glucose and oxygen. With cellular respiration, its the opposite. Glucose + oxygen to break it down and forms waste products of 6 carbon dioxide and 6 water. The main thing it produces though is ATP (Adenosine Triphosphate). ATP is the product of cellular respiration and is fuel for your cells to function. I hope this helps. There are different stages in photosynthesis and cellular respiration that I’m not going to dive into, but this is the main reason why they depend on each other. Because unlike humans where we eat food, they use photosynthesis to make their glucose which they turn into ATP energy. Think I covered most of it. Good luck on your presentation!
