Global Carbon Cycle
The Global Carbon Cycle is the continuous movement of carbon among the Earth's atmosphere, oceans, soil, and living organisms. Carbon exists in various forms, like carbon dioxide (CO2) in the air, organic matter in plants and animals, and fossil fuels underground. Plants absorb CO2 during photosynthesis, while animals release it through respiration. Human activities, such as burning fossil fuels and deforestation, add extra CO2 to the atmosphere, contributing to climate change. Understanding this cycle is crucial for managing carbon levels and addressing environmental issues like global warming.

The global carbon cycle is the process by which carbon atoms move between the Earth's atmosphere, oceans, soil, and living organisms. Carbon is found in carbon dioxide (CO2) in the air, and plants absorb it during photosynthesis to produce oxygen and food. Animals consume plants, and when they breathe or decompose, carbon returns to the atmosphere. Oceans also absorb CO2, playing a crucial role. Human activities, particularly burning fossil fuels, add excess carbon to the atmosphere, contributing to climate change. Understanding this cycle is vital for managing our planet's health and addressing environmental challenges.
