Ecology is largely NCERT-driven. Population growth (exponential, logistic), community interactions (mutualism, competition, predation), ecosystem energy flow (10% law, ecological pyramids), biogeochemical cycles (carbon, nitrogen, water), and biodiversity hotspots/IUCN classifications all appear regularly.
