Class 12 Biology notes on Ecosystems and Biodiversity for NEET UG. Covers the structure of an ecosystem, productivity, decomposition, food chains and energy flow, the ten percent law, pyramids of number, biomass and energy, ecological succession, the carbon and phosphorus cycles, patterns of biodiversity, causes of its loss and in-situ and ex-situ conservation, with pyramid and cycle diagrams, tables and practice questions. Includes 6 labelled diagrams: Steps of decomposition; A grazing food chain. Each step passes on about 10% of the energy; Pyramid of energy.
