1. The largest group in Linnaeus's seven-level classification system is

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic

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
