In 1977, there was a drought on the island. The vegetation disappeared and only cactus remained. What was the finches only food source?

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.
