Sun is the primary source of energy. There exists some loss of energy when the energy transfers through successive trophic levels. ... So the energy would be always decreasing as we go to higher trophic levels, it can never d ecrease. Therefore, we cannot have an inverted pyramid of energy.
The correct answer is that the H zone becomes narrower.
The H-band refers to the region of the thick filaments, which is not overlaid by the actin (thin filaments). Within the H-zone is a thin M-line, which is formed of cross-connecting components of the cytoskeleton.
At the time of muscle contraction, the A-bands do not vary in their length, whereas the H-zone and the I-bands shorten. This makes the Z-lines come near to each other.
