Match List I with List II LIST I (Terminology) LIST II (Related Aspects) A. Biogeochemical cycles I. Ecosystem productivity B. Flow of Energy II Nutrient cycles C. Biomass III. Trophic Pyramid D. Food chain IV. Law of Thermodynamics Choose the correct answer from the options given below:
A - II, B - IV, C - I, D - III
The matches are A–II, B–IV, C–I, D–III. Biogeochemical cycles recycle nutrients; energy flow obeys thermodynamic laws; biomass is related to ecosystem production; and food chains identify trophic levels represented in ecological pyramids. Biomass is a standing stock, whereas productivity is a rate of biomass production.
