The article explores how elements like hydrogen, oxygen, nitrogen, sulfur, phosphorus, iron, mercury, cadmium, and lead cycle through the environment and impact life on Earth. Researchers studied how these elements interact with living organisms and the planet over long periods of time. They found that these biogeochemical cycles play crucial roles in the evolution of life, growth of phytoplankton, and the health of ecosystems. The study sheds light on how elements move through the environment and influence the Earth's systems.
