How does photosynthesis benefit the environment?

Photosynthesis benefits the environment by producing oxygen and reducing carbon dioxide levels in the atmosphere. Green plants, algae, and some bacteria convert sunlight, water, and carbon dioxide into glucose and oxygen. This process forms the foundation of the food chain, supporting nearly all life on Earth. Photosynthesis also helps regulate the global carbon cycle, mitigating the effects of climate change. Forests, grasslands, and marine phytoplankton are significant contributors to this process. Additionally, photosynthesis provides the organic matter that fuels many ecosystems and sustains agricultural productivity.
