In an ecosystem, a sudden decrease in the number of bacteria in the soil would most likely result in

Bacteria in the soil, are responsible for the process of nitrogen fixation. It aids in the conversion of atmospheric nitrogen into nitrogen-containing compounds (like ammonia) that can be used by plants. If there will be a sudden decrease in the number of bacteria in the soil there will be lesser nitrogen supply for plants and organism, air and water which comprise our ecosystem.

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
