how much energy is lost 4rm producers to secondary consumers? I think between 80 and 90 percent.

Answer 1

What does 4rm mean? Who are secondary consumers? Consumers of what?

Answer 2

from I bet :) (although I do not do texting)

Do you mean for example from a coal mine to a residential electricity consumer? If that is the case perhaps your 80 to 90 percent is reasonable.
If you just mean from the generator to the house I would guess closer to 50%

Answer 3

Secondary consumers = Carnivores = frog

Secondary consumers eat herbivores.
