In any heat engine there is always some rejection of heat to the environment. Thus an internal combustion engine, as in a car, rejects heat in its exhaust gases, and also loses heat into its radiator. An aircraft jet engine rejects heat at its exhaust, it is impractical to extract more energy from this. In a power plant the steam turbine rejects heat to its condenser in order to condense the exhaust steam to water for feeding back to the boilers.
Heat energy is a wasted form of energy given out by a hairdryer. A significant amount of the electricity consumed by a hairdryer is converted into heat to dry the hair, making it an inefficient use of energy.
No, it is not possible to entirely convert a given amount of heat into mechanical energy due to inefficiencies and losses in the conversion process, as described by the second law of thermodynamics. Some heat will always be lost to the surroundings as a byproduct during the conversion process.
The energy produced when 1kg of a substance is fully converted into energy is given by Einstein's famous equation E=mc^2, where E is the energy produced, m is the mass of the substance (1kg in this case), and c is the speed of light. This equation shows that a large amount of energy can be generated from a small amount of mass.
The amount of energy stored in the batteries is typically higher than the total amount of light output by the flashlight, as some energy is lost as heat during the conversion process. The efficiency of the flashlight will determine how much of the stored energy is actually converted into light.
When energy is given off by splitting atoms, it is converted from nuclear energy to thermal energy. This thermal energy is then used to heat water and turn it into steam, which can be used to drive turbines and generate electrical energy, converting the thermal energy into mechanical and then electrical energy.
Strictly speaking, it's not. It's connected to the fact that the mechanical energy can be converted to IR radiation (or other kinds of EM waves), or it can be converted to the vibrations of the material's lattice and so on.

yes you can

The amount of chemical energy in consumers' food that is converted to their own new biomass during a given time period is known as Net Primary Productivity (NPP). It represents the energy that is available to the next trophic level in an ecosystem for growth and reproduction.

The term for the amount of biomass produced in a given area is "primary productivity." It refers to the rate at which energy is converted into organic substances by autotrophic organisms through photosynthesis or chemosynthesis.

heat
Most energy is given off as heat, which is a form of energy that is transferred from one object to another due to a difference in temperature. When energy is transferred or converted from one form to another, some amount of energy is usually lost as heat.
An electric generator produces electrical energy. It converts mechanical energy to electrical energy by interacting with a magnetic field. The amount of electrical energy converted to useful work in a given time interval is the power output. If the generator is not connected to any load, then no work is done and there is no power.
