U1.3 Nitrogen and Phosphorus Cycles
Trace nitrogen through fixation, ammonification, nitrification, assimilation, and denitrification. Trace phosphorus through weathering, plant uptake, decomposition, sedimentation. Identify human disruptions (fertilizer runoff → eutrophication; mining; combustion).
What you'll do in this lesson
A voice-first session with the Crimsora tutor on U1.3 Nitrogen and Phosphorus Cycles, then targeted practice and FRQs — with the tutor adapting to where you get stuck.
