It in takes 10% of the energy from the lower trophic level organism.
The percentage of energy in one trophic level that transfers to the next level in the average ecosystem is?
Studies of a variety of communities indicate that the net transfer of energy between tropic levels is roughly 10% efficient, although transfer among levels within different communities varies significantly.

1%
Why are the numbers of trophic levels limited?
At each trophic level in a food chain, a large portion of the energy is utilized for the maintenance of organisms which occur at that trophic level and lost as heat. As a result of this, organisms in each trophic level pass on less and less energy to the next trophic levels, than they receive.

No, Trophic level is the level it is in in the food chain depending on its habitat.
