IF most of the energy we use on earth comes from the sun – how does that energy (light and thermal) end up As energy in our food As energy of wind or moving water As energy that powers our lights As energy when we move around
Answers
The correct options to the question will be:
Chemical energy.
Kinetic energy.
Electrical energy.
Mechanical energy.
It should be noted that the energy held in food is called chemical energy. It is simply a form of potential energy that is held within chemical bonds.
The energy of the wind or moving water is kinetic energy. The energy that powers out light is electrical energy while the energy that we use when we move around is mechanical energy.
The energy from the sun reaches the Earth in the form of light and heat. This energy is then transformed into various forms that can be used by living beings and humans.
Plants use the energy from the sun through the process of photosynthesis, which converts the light energy into chemical energy stored in the bonds of organic molecules such as glucose. When animals and humans eat plants, they get energy from these organic molecules.
The energy from the sun also drives the wind and water currents, which can be harnessed to produce wind power and hydroelectric power. These forms of renewable energy are used to generate electricity and provide energy for various purposes.
In addition, the energy from the sun can be used directly to power lights, such as in solar-powered lamps. The light energy is captured by solar panels and converted into electrical energy that can be stored in batteries for use at night or during cloudy days.
Finally, when we move around, we use the chemical energy stored in our food to fuel our movements. Our bodies break down the glucose in our food and release the stored energy to power our muscles.
In conclusion, the energy from the sun reaches the Earth in the form of light and heat, and it is transformed into various forms of energy that can be used by living beings and humans, including energy in food, wind and water power, light energy, and energy for movement.
