bio-geo chemical cycle explains own words?
Answers
Answer:
Explanation:
The Earth is a closed system for matter, except for small amounts of cosmic debris that enter the Earth’s atmosphere. This means that all the elements needed for the structure and chemical processes of life come from the elements that were present in the Earth’s crust when it was formed billions of years ago. This matter, the building blocks of life, continually cycle through Earth’s systems, the atmosphere, hydrosphere, biosphere, and lithosphere, on time scales that range from a few days to millions of years. These cycles are called biogeochemical cycles, because they include a variety of biological, geological, and chemical processes.
Answer:
both non living ( abiotic ) and living (biotic) components of biosphere constantly interact with each other to form a dynamic and yet stable system. Such interaction include transfer of matter and energy between the different components of biosphere
