Learn about the nitrogen cycle, including the steps of the cycle and the impact of human activities on these processes. Nitrogen cycle is the natural process by which atmospheric nitrogen is converted into various usable forms, like ammonia and nitrates, by bacteria for plant and animal consumption and then returned to the atmosphere through decomposition and denitrification, maintaining the nutrient balance in ecosystems. Nitrogen is an essential element for life as it is a key component of amino acids, proteins, DNA, and other biological molecules. Human activities, like agriculture and industry, can ...
