The video explains the nitrogen cycle, highlighting how nitrogen is essential for life but cannot be used directly by plants and animals. It describes the conversion of nitrogen gas into usable compounds by nitrogen-fixing bacteria in the soil and legumes. Plants absorb these nitrates to make proteins, which are then passed through the food chain. Decomposition returns nitrogen to the soil, where bacteria convert it into ammonium ions and then back into nitrates. Finally, denitrifying bacteria transform nitrates into nitrogen gas, completing the cycle.
