I am doing a project Energy Transformation Illustration. I picked a gas stove for this project. I have to draw three thing to show its transformation. What I have to draw for first and second transition? Third is gas stove. Plz help.

nuclear energy from the Sun (in the form of light) is transformed into chemical energy by plants (photosynthesis)

the plants (and the animals that eat them) eventually become fossil fuels (gas, oil, coal, etc)

the chemical energy stored in the gas is converted to heat energy by the stove
