hiiliketjun

Hiiliketjun is a Finnish term that translates to "carbon chain" or "carbon loop." In an ecological context, it refers to the biogeochemical cycle of carbon, encompassing the processes by which carbon atoms move through Earth's atmosphere, oceans, land, and living organisms. This cycle is fundamental to life on Earth, influencing climate and the availability of nutrients.

The carbon cycle involves several key components. Photosynthesis by plants and phytoplankton removes carbon dioxide from the atmosphere, converting it into organic compounds. Respiration by living organisms, including animals and microbes, releases carbon dioxide back into the atmosphere. Decomposition of dead organic matter also returns carbon to the soil and atmosphere.

Human activities, such as the burning of fossil fuels and deforestation, have significantly altered the natural carbon cycle, leading to an increase in atmospheric carbon dioxide concentrations. This imbalance is a primary driver of climate change. Understanding the hiiliketjun is crucial for addressing environmental challenges and developing sustainable practices. Scientists study various aspects of the hiiliketjun, including carbon sequestration in forests and oceans, and the impact of human emissions on global carbon budgets.
