Yes, running a computer will consume more energy than when it is turned off or in sleep mode. The amount of energy consumption will vary based on the computer's usage, specifications, and power settings. Properly shutting down or putting a computer in sleep mode when it's not in use can help save energy.
They don't.
plants gain energy from the sun during photosynthesis, this energy is then passed on to insects as they consume the plants, then a bird will eat the insect and so on. But energy is lost at each stage of consumption as movement, heat and in faeces. so in order for living things to get enough energy they must consume more. See a pyramid of Biomass for this process.
Turning off your computer when not in use saves more energy compared to leaving it on. The amount of energy used to start up a computer is minimal compared to the continuous energy consumed when the computer is left running. It is typically recommended to turn off your computer when it will not be in use for an extended period to save energy.
Computer monitors typically consume around 30-60 watts of electricity, depending on the size and type of the monitor.
One kilowatt-hour, or KWH.Additional AnswerYou don't 'consume power'; you consume energy. Power is a measure of the rate at which you consume energy.
Computers do not produce energy, they use/consume energy.

A computers energy source is electricity. When using a computer plugged in or not it is drawing electricity from the battery or from a plug which is connected into the PC and a wall outlet. When there is no electricity the computer cannot function.
It would consume more fuel - as it would need to expend more energy to fight against the headwind.
yes
Energy expenditure comes from day-to-day activities as well as your body keeping an internal temperature of about 98.6 degrees Fahrenheit. Ideally, you will consume and expend and equal amount of energy. However, if you consume more than you need, your body will have too much energy, storing it as glycogen or fat. More energy must be expended than consumed in order to deplete these energy reserves.
chemistry? more specific please
If no, or few, applications are left up and running a computer will not consume much power when left on. Computers in general consume less power then a single light bulb when running. At idle they may go down to as little as 30 watts depending on age, speed and configuration of the computer.
It probably takes less energy, but it depends on the efficiencies of various components in the computer, charger, and MP3 player. Chargers convert the electricity less time than a computer, so they are generally more efficient. Good chargers also consume very, very small amounts of parasitic power when they are not charging...not enough to worry about.
