I don't know what situation you are thinking of. The use of energy does correspond to doing work. You may be thinking of sitting quietly in a chair reading, not using any energy yourself (apart from your own internal metabolism), whilst your heating system keeps you warm. It may seem that no work is being done, but in fact your surroundings are losing heat continuously to the external of your house. That flow of heat is equivalent to mechanical or electrical energy through the relation 1 calorie = 1 Joule, or 1 BTU = 1055 Joules if you like BTU's. So even if mechanical work is not apparent, your use of heating BTU's is in effect doing work.
If this does not answer your question please submit another one but try to specify what situation you are thinking of
Potential energy is energy related to a position. If you put an object to a higher position (pushing it against the force of gravity), it will have more potential energy. If it falls down, this energy can again be converted into another kind of energy. While the object is high (say, on a shelf), the energy is stored as potential energy.
Having said that, one could nevertheless argue that all energy does involve motion somehow, on some scale. Thermal energy (heat) involves motion of the individual atoms and molecules. Nuclear energy involves the motion of subatomic particles. Chemical energy involves the motion of bound electrons between atoms. Electromagnetic energy (including light) involves the motion of photons. Electrical energy, by its very definition, involves the motion of free electrons. Acoustic energy (sound) involves the periodic motion of air (or other medium) molecules as waves pass through them. Even potential energy had to invovle motion at some time in order to position an object such that it now has potential energy.
Lost: no. Used up: yes.
To be more precise, energy can't be destroyed - the total amount of energy remains constant. However, it is possible to convert useful energy into unusable energy. In fact, this happens all the time.
nope, some energy's do not require motion!
no
Only if properly directed.
Yes
Energy isn't "used up" but instead is converted into different forms like heat (thermal) and motion (kinetic) but when talking about an object we say the object has lost or gained energy.
The energy that is lost in the energy pyramid is mainly released as heat through metabolic processes. As energy is transferred between trophic levels, not all of it is consumed and therefore some is lost as heat energy. This ultimately contributes to the second law of thermodynamics which states that energy in a system tends to disperse and degrade over time.
10%
Typically, around 10% of energy is transferred up the energy pyramid from one trophic level to the next. This is due to the inefficiency of energy transfer through biological systems, with most energy being lost as heat or used for metabolic processes.
No, energy decreases as you move up an energy pyramid due to the second law of thermodynamics. Each trophic level only retains about 10% of the energy from the level below it, with the rest being lost as heat or used for metabolic processes.

energy is lost in Bio-fuels by the energy and the fuel used in biofuel to burn heat

what happened to the energy that is not stored in your body
Basically only 1/10 of the energy from the previous organism is absorbed into the body of the consumer while the other 9/10 is burned up when used for energy by the previous organism. If there is some grass with 100 energy and it gets eaten by a herbivore, the herbivore only receives 10% of the ORIGINAL energy (so the herbivore will have 10 energy.) The animal that will eat the herbivore will only receive 1 energy from the ORIGINAL energy source. The next consumer of the previous organism will only get 0.1 energy from the ORIGINAL energy source and so on.
lost as heat or used
10% of energy is lost as you move from 1 level to the next. So at the end 90% if the energy will be lost as heat.
Because a lot of the energy used to hear up the room is lost to the surroundings eg for every 100 J of energy stored in coal and released as heat about 25 J is used to heat u the room whilst the rest is lost to the surroundings
They eat to make up the energy they lost
