What percent of energy is transferred between the levels indicated by the blue arrows?
a. 50
b. 90
c. 100
d. 10

d)10%

this is due to the fact that energy is lost from organisms through respiration and excretion so that each member progressively receives less biomass and energy. also the members of the trophic levels decrease as you go up a food chain

the genotypes would be 50% bb and 50% bb

the phenotypes would be 50% brown and 50% white. hope this : )
