The fleas benefit the dog true or false?

false

Only the fleas benefit from being on the dog. Therefore, it is a parasitic relationship because one organism in the relationship is harming the other in the relationship for its own benefit. Also that animal (the fleas) would have to find a new home if its host dies, as it cannot live without it. :)

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
