The chemical energy is inefficiently converted into usable energy by respiration because all the stored energy is not converted into ATP. Some of it is released into the ecosystem as.

heat. This is due to the fact that not all of the chemical energy stored in glucose molecules can be fully captured and converted into ATP during the process of cellular respiration. Some energy is lost as heat during the various steps of glycolysis, the citric acid cycle, and oxidative phosphorylation.

Additionally, there are inefficiencies in the conversion of potential energy in glucose to chemical energy in ATP. For example, some energy is required to transport molecules across cell membranes, and some energy is lost as electrons move through the electron transport chain. These inefficiencies result in a loss of energy that is not converted into ATP and instead is released as heat.

Overall, respiration is an inefficient process in terms of energy conversion, with only about 38% of the energy in glucose molecules being converted into ATP. The rest is lost as heat, which is why our bodies produce heat as a byproduct of metabolism.
