Photosynthesis: The Engine of Life on Earth
Introduction: In the complex web of life on our planet, few processes hold as much significance as photosynthesis. At its core lies an apparently ordinary gas: carbon dioxide (CO2). Through the incredible power of photosynthesis, plants, algae, and certain bacteria harness the energy of sunlight, combining it with water and CO2 to orchestrate a symphony of life-sustaining reactions. This process not only fuels the growth and vitality of these organisms but also serves as the foundation of the entire biosphere, providing food, energy, and oxygen for countless species. Let's explore the compelling reasons why photosynthesis, with carbon dioxide at its core, truly stands as the engine of life on Earth.
Graphical History of CO2 in our Atmosphere
As the second most prevalent greenhouse gas in our atmosphere (after water vapor), carbon dioxide (CO2) has become a crucial indicator of climate change. Throughout the Earth's 4.54 billion-year history, CO2 levels have fluctuated significantly, contributing to our planet's average temperature shifts.
