The video explores the five main biogeochemical cycles crucial for life on Earth: water, carbon, oxygen, nitrogen, and phosphorus. It delves into the processes involved in each cycle, emphasizing their importance in sustaining ecosystems and the role of environmental engineering in their conservation.

Biogeochemical processes involve essential chemical elements like carbon, nitrogen, phosphorus, and others serving as nutrients for living organisms. These elements move between living beings and the abiotic environment to sustain life, balance, and ecosystem health through five main cycles: water, carbon, oxygen, nitrogen, and phosphorus.

The carbon cycle is a natural process involving the constant transfer of carbon between the atmosphere, oceans, biosphere, and lithosphere. It consists of five phases: photosynthesis, respiration, decomposition, and combustion, playing a crucial role in sustaining life on Earth and impacting environmental engineering.
