süsinikutsüklit

süsinikutsüklit, also known as the carbon cycle, is the process by which carbon atoms continuously travel from the atmosphere to the Earth and then back into the atmosphere. This cycle is essential for life on Earth as it regulates the planet's temperature and provides the building blocks for organic molecules.

The carbon cycle involves several key reservoirs where carbon is stored, including the atmosphere, oceans, land, and living organisms. Carbon moves between these reservoirs through various processes. Photosynthesis is a primary mechanism by which carbon dioxide is removed from the atmosphere and converted into organic compounds by plants and other photosynthetic organisms. When these organisms die, decomposers break down their organic matter, releasing carbon back into the soil and atmosphere.

Respiration, carried out by both plants and animals, releases carbon dioxide into the atmosphere. The oceans play a significant role in the carbon cycle, absorbing large amounts of atmospheric carbon dioxide and releasing it back. This process can occur through direct diffusion and via marine organisms.

Human activities, particularly the burning of fossil fuels and deforestation, have significantly impacted the natural carbon cycle. These activities release large quantities of stored carbon into the atmosphere, primarily as carbon dioxide, leading to an increase in greenhouse gases and contributing to climate change. Understanding and managing the carbon cycle is crucial for maintaining a stable climate and a healthy planet.
