karbonkörforgáshoz

The carbon cycle, or karbonkörforgás in Hungarian, is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. It is one of the most important of Earth's biogeochemical cycles. This cycle involves a continuous movement of carbon from the atmosphere to the Earth and back again.

Key processes within the carbon cycle include photosynthesis, respiration, decomposition, combustion, and geological processes. Plants absorb carbon dioxide from the atmosphere through photosynthesis, converting it into organic compounds. Animals obtain carbon by consuming plants or other animals. Respiration by plants, animals, and microorganisms releases carbon dioxide back into the atmosphere. Decomposition of dead organic matter also returns carbon to the soil and atmosphere.

Human activities, particularly the burning of fossil fuels and deforestation, have significantly altered the natural balance of the carbon cycle. This has led to an increase in atmospheric carbon dioxide concentrations, contributing to climate change. Understanding the carbon cycle is crucial for addressing environmental challenges and developing sustainable practices to mitigate the impact of human activities on the planet's climate system.
