Photosynthesis, the vital process in plants, converts raw materials—carbon dioxide and water—into glucose, releasing oxygen. It occurs within chloroplasts, the site of photosynthesis. The process involves interconnected events, including light absorption, energy conversion, and carbon dioxide reduction. Factors like light intensity, temperature, and nutrient availability influence photosynthesis. Unique adaptations in desert and aquatic plants optimize their photosynthetic efficiency

Autotrophs, such as plants, algae, and chemosynthetic bacteria, synthesise their own food.

Autotrophs fuel the development of ecosystems and provide essential nourishment for heterotrophs.
