Um I just need help

for the points

ecological efficiency: % of usable energy transferred as

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 

gag reflex, poor dentition, gum retraction
