Which of the following equations follows the Law of Conservation of Mass? A. H2 + O2 2OH
B. CH4 + 3O2 2CO2 + 2H2O
C.2Mg + Cl MgCl2
D.2Fe + 3O2 Fe2O3

answer; ///i believe that the correct answer is (a) specialized cells)

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
