That some organisms contain much larger amounts of dna than are apparently "needed" and that some relatively closely related organisms may have vastly different amounts of dna is more typical in

meiosis is the correct answer

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
