Exploring Biogeochemical Cycles in Biology

The video covers biogeochemical cycles, including the water, oxygen, carbon, phosphorus, and nitrogen cycles. Each cycle is explained in detail, highlighting key processes like evaporation, photosynthesis, and nitrogen fixation. The video also discusses human impacts on these cycles and the importance of maintaining balance in the environment.
