If the original amount of energy found in the producer trophic level is 100 kcal how much iS passed on to the primary consumer trophic level? How does this amount limit the number of members in the next higher level?

it restores trees to areas where they once grew.

2%? i tried finding the exact sorry if it's not 100% correct ; -;

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
