to all of those doing your science homework at the last minute and thinking you will get the answer. well i dont know the answer so go and look somewhere else :)
Biologically speaking, through heat radiation, death, excretion and metabolic processes (which pretty much means heat radiation).
A great deal of energy is lost in the form of heat.
According to the law of conservation of energy, energy can't really get lost. The term "lost energy" really refers to energy changing from a high-value form to a lower value form, i.e., to a form in which it is no longer useful.
Heat or light. By the way, the energy is not 'lost', but rather turned into a different form of energy.
mostly heat energy
Energy conversion is not really efficient because of many factors. If we take an example of how energy are lost during conversion in our power plant. Today the efficiency rate for our coal powered plant are only 20-40%, which is an absolute waste. All those 60 or more % of energy lost is because they are converted from one form to another form many times before result is seen. Energy can be lost in forms of heat, sound mainly.
Energy is neither created nor destroyed by chemical processes, merely transferred. Since energy is also lost every time energy is transferred between organisms, that lost heat must go somewhere. That lost energy becomes waste heat in the environment.
Energy can be lost in a food chain by heat or waste.
energy of a reaction will be lost in the form of heat.
A great deal of energy is lost in the form of heat.
Energy is lost as heat during respiration.
Between producer and secondary consumers very little energy is lost to heat and waste. More energy is lost by keeping the organism alive than is lost to the environment.
Lost To The Environment As Heat

Final end of all energy lost is thermal energy. Thermal energy is the least valuable energy. The concept of entropy is rely on the loss of working capability of the system to the thermal energy. In general, the term for thermal energy lost can be called waste heat.
