Explanation:

Mycelium, the body of a fungus is multicellular. The mycelium is made of many hypha. Each cell of a hypha possesses cell wall but lack chloroplast. The cell wall is made of chitin, a type of polysaccharides not made of cellulose as in green plant cells. Due to lack of chloroplast, fungi are heterotrophs.

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
