Biogeochemical Cycles

Step 1: Understanding the Concept:
Nutrient cycles (or biogeochemical cycles) can be broadly classified into two types: 1. Gaseous cycles: The main reservoir of the nutrient is the atmosphere or hydrosphere (e.g., nitrogen, carbon, oxygen cycles). 2. Sedimentary cycles: The main reservoir of the nutrient is the lithosphere (soil and rocks) (e.g., phosphorus, sulfur, calcium cycles).
