Eating an apple will add to your energy stores; riding a bike will deplete them.
Energy conversions take place inside your body's cells, specifically in the mitochondria, where food molecules are broken down to release energy in the form of ATP (adenosine triphosphate). This energy is then used to power various cellular processes and activities.
The main energy conversion is from chemical energy stored in the battery to electrical energy. The electrical energy powers the light bulb to produce light and heat energy.
The energy conversions that take place in this scenario are: 1) Thermal energy from boiling water is converted to kinetic energy when the steam is blown against the turbine blades, causing them to spin; 2) The kinetic energy of the spinning turbine blades is then converted to electrical energy as the blades interact with the magnetic field to generate electricity; 3) Finally, this electrical energy powers the lamp, converting it into light energy for illumination.
In a pendulum, potential energy is converted to kinetic energy as it swings back and forth. Friction and air resistance gradually dissipate the kinetic energy, causing the pendulum to eventually stop swinging.
When you vigorously rub your hands together, mechanical energy is converted into thermal energy through the friction generated between your hands. The kinetic energy of the movement is transformed into heat energy, causing your hands to warm up.

Chemical energy to thermal energy to mechanical energy to electrical energy
Potential to kinetic to electric energy conversion takes place when a rubber powered aeroplane flies.
The main energy conversion is from chemical energy stored in the battery to electrical energy. The electrical energy powers the light bulb to produce light and heat energy.
Combustion. The carbon-matter and oxygen combust, releasing CO2, N, and heat.
In this scenario, the boy's body converts the potential energy from the apple into kinetic energy to lift the weights. The chemical energy in the apple is transformed into mechanical energy as the boy's muscles contract to exert force on the weights. This process involves a series of energy transformations from potential (stored in the apple) to kinetic (muscle movement).
