Approximately 200 million years ago, during the Mesozoic Era, bacteria played a critical role in nutrient cycling and the decomposition of organic matter, which was essential for maintaining ecosystem balance. They facilitated the breakdown of complex organic materials, releasing nutrients back into the soil and water, thereby supporting plant growth and the diverse animal life that depended on these plants. Additionally, certain bacteria contributed to the formation of essential resources, such as fossil fuels, which were formed from ancient organic matter. Overall, bacteria were vital for sustaining life and shaping the environment during this period.
