Water and Nitrogen Cycle Concepts

Chloe introduces nitrogen and the water cycle, explaining their significance and processes. The nitrogen cycle includes fixation, denitrification, ammonification, and nitrification, while the water cycle involves evaporation, transpiration, condensation, precipitation, and collection. Both cycles are crucial for life on Earth.
