The A horizon is the best for plant growth, because is has more organic material and more organisms that make the soil more fertile than the deeper layers, and the soil is not loose like the O horizon.

the A horizon

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

what's the question ?
