náttúrukerfi

Natturukerfi is an Icelandic term that translates to "natural system" or "ecosystem." It refers to the complex, interconnected network of living organisms (biotic components) and their physical environment (abiotic components) within a specific area. This encompasses everything from the smallest microorganisms and plant life to large animals, soil, water, air, and sunlight. The interactions between these elements are crucial for the functioning and sustainability of the natturukerfi.

These systems operate through various cycles, such as the water cycle, carbon cycle, and nutrient cycles, which continuously move and transform matter and energy. The health and stability of a natturukerfi depend on the balance of these interactions. Changes to one component can have cascading effects throughout the entire system, potentially leading to significant alterations. Human activities, including pollution, habitat destruction, and climate change, are major factors influencing natturukerfi worldwide. Understanding and preserving these natural systems is vital for maintaining biodiversity and the provision of essential ecosystem services upon which all life, including human society, depends.
