According to scientific estimates, over 60% of newly fixed nitrogen each year is assimilated by microorganisms, highlighting the vital importance of this process for life on Earth. This essential biological function is known as assimilation in the nutrient cycle, and it ensures that inorganic elements are converted into usable organic matter for growth and development.

Over 99% of all life on Earth relies on the sun's energy, which is captured by photosynthetic organisms to fuel its existence, from the smallest algae to the largest predators. The question of the ultimate food source is a fundamental concept in biology and ecology that explains how ecosystems are powered and sustained.

Over 4.5 billion years ago, simple building blocks of life emerged, but where did the first proteins originate? The ultimate source of all protein begins not in animals, but with the fundamental chemistry of early Earth and continues today with microscopic organisms and plants that produce the amino acids essential for life.
