Explanation: I just had this question :)
The gas which is released at cathode is hydrogen, H2 and the gas released at anode is oxygen, O2. ... Therefore after electrolysis the water volume of one gas collected at one electrode is double (hydrogen gas) of anode (oxygen gas).
Answer: some energy is lost from the pyramid, energy is transferred from bottom (producers) to top, but in decreasing amounts.
Explanation: total energy is conserved, but not necessarily within the energy pyramid, which is an open system where energy is lost from the pyramid, mainly as heat but also as sound.
Energy is transferred up the pyramid but the amount transferred at each stage is less because of losses outside the pyramid.
