The trophic levels show which organisms are at each level of the energy pyramid. The pyramid is shaped exactly as a pyramid. The lowest level contains the most energy and the most in number and variation of species. The next level only has 10% of the first levels' energy and fewer species. The amount of energy in the first level determines the number of levels possible. The tropical rain forest has the most levels (as many as 4) and a desert has the fewest (as few as 2). See links below:
Trophic levels and food chains are connected in number of ways. Trophic levels show the energy transfer throughout the species in different food chains.
A food chain runs off of different levels - each having one living organism in it, per food chain. The levels indicate a section where energy is used up by an organism - namely the one that attained the energy.

Decrease in higher levels.
The number of links in a food chain is ultimately limited by the amount of energy in the producers of the particular ecosystem.
Energy pyramid Apex^^^^^
the energy of a food chain goes down as it moves up the food chain. so the primary producer has the most energy and the quaternary consumers have the least amount of energy. -kait B :)
