Each level of an energy pyramid is smaller because energy is lost as it moves up the food chain. Organisms use some energy for growth, movement, and other life activities, and this energy is lost as heat through respiration. This means there is less energy available for the next trophic level.
Depends on what one means by "smaller". Since sublevels are "inside" or part of the principle energy level, then yes, they are smaller.
As the levels progress upward in a pyramid form, only 10% of the energy level below can be transfered as energy to the next level. Using the lowest level as having 100%, the next level only has 10% of that 100% to use for energy. The third level will have 10% of 10% of that 100% to use for energy. Because there is only so much at each level to use, the number of animals and plants become smaller. At most there will be 3 levels. A very few will reach 4 levels.
The most energy is available at the producer level of the pyramid . As you move up the pyramid, each level has less energy available than the level below.
Each level in a food chain contains less energy because energy is lost as heat through metabolic processes like respiration and digestion as it moves up the chain. This means that less energy is available for transfer to the next level.
They are smaller in magnitude than those between lower energy levels.
Sub energy pretty much explains itself: It is below energy level

The biomass of a species decreases with increasing trophic level due to energy loss along the food chain. Each trophic level consumes energy and nutrients from the level below, resulting in a smaller overall biomass at higher trophic levels. This is known as the 10% rule, where only about 10% of energy is transferred from one trophic level to the next.

A consumer depends on the trophic level below it for energy.

Yes. Any object that is above a reference level has positive potential energy; anything below that reference level has negative potential energy. For example, if the chosen reference level is the ground level, anything below the ground level has negative potential energy. Please note that the choice of reference level is arbitrary. What matters is the DIFFERENCE in potential energy between two positions - and that doesn't change, whether you choose (for example) the ground level, or some other level, as a reference level.
This is because energy is lost at each trophic level (from all the activity done by that level, e.g., running, climbing, fighting) . The energy available to the next trophic level is about 10% of the energy of the previous trophic level.

Yes, because the organism at the first feeding level has used some of the energy for its own growth, respiration, warmth etc, reducing the amount of energy available for the second feeding level.
