Decomposition & Nutrient Cycling

Decomposition and nutrient cycling are fundamental concepts in ecosystem ecology and frequently asked in CSIR-NET Life Science exams. In this video, we break down the 5-step decomposition process—fragmentation, leaching, catabolism, humification, and mineralization—and connect it to biogeochemical cycles of carbon, nitrogen, and phosphorus. Learn how nutrients flow through ecosystems, the role of microbes, and key differences between gaseous and sedimentary cycles. With infographic-based learning, exam insights, and common traps, this session will boost your conceptual clarity for Part B and Part C questions. 📘🌱 #CSIRNET #CSIRNETLifeScience #EcologyConcepts #BiogeochemicalCycles #NutrientCycling #LifeScienceExam #NETPreparation
