What is photosythese and respiration?

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose. This process occurs mainly in the chloroplasts and involves the uptake of carbon dioxide and water, releasing oxygen as a byproduct. Respiration, on the other hand, is the metabolic process by which organisms break down glucose and other organic molecules to produce energy in the form of ATP, using oxygen and releasing carbon dioxide and water. Together, these processes are essential for the energy flow and cycling of matter in ecosystems.
