The geological cycle does not involve living organisms. This cycle includes processes such as the rock cycle, hydrological cycle, and tectonic activity, which are primarily driven by Earth's physical and chemical processes rather than biological ones. While living organisms can influence certain aspects of the environment, the fundamental processes of the geological cycle operate independently of biological life.
Processes are considered inorganic when they do not involve living organisms or organic compounds as essential components. Inorganic processes often rely on non-living materials such as minerals, gases, or metals, and typically do not involve biological or biochemical reactions. Examples include chemical reactions like precipitation, crystallization, or combustion.
Non-biological factor (such as sunlight), material (such as sulfur dioxide), or process (such as hydrolysis) which can affect living or non-living constituents of an ecosystem. Opposite of biotic.
Inorganic processes involve chemical reactions or physical changes that do not involve organic compounds or materials derived from living organisms. These processes typically involve elements or compounds that are not based on carbon-hydrogen bonds, such as minerals, metals, or gases like oxygen and nitrogen. Examples include precipitation reactions, redox reactions, or crystallization of minerals.
No, chemical reactions occur in both living and non-living systems. In living organisms, chemical reactions are essential for metabolic processes, while in non-living systems, chemical reactions can occur in various environments such as inorganic chemical reactions in the environment.

Biological catalysts
metabolism
Biochemistry is the study of chemical processes that occur within living bodies. It involves the study of internal chemical processes and how they relate to the organism's life as well as the chemical composition of an organism.
Enzymes are proteins that catalyze chemical reactions in living organisms, influencing all chemical processes. Hormones, such as insulin, thyroid hormone, and adrenaline, also play a key role in regulating various physiological processes in the body. Together, enzymes and hormones help control and coordinate the vast array of chemical reactions that occur in living organisms.
Energy flow on Earth is primarily driven by the sun through photosynthesis, where plants convert sunlight into chemical energy. Chemical cycling is driven by biogeochemical processes, such as the carbon, nitrogen, and water cycles, which involve the movement of elements and compounds between living organisms, the atmosphere, soil, and water bodies. These processes are essential for sustaining life on Earth.
