Energy Transformation takes places when energy changes from
one form to another.
Not all forms of energy are directly useful to
organisms so they must be transformed into a
useful form.
Example
In photosynthesis plants can’t store the sun’s
light energy in their cells. The energy is
transformed into chemical energy so it can be
stored.
Some energy in a transformation is lost to the
environment as heat or sound.
Some energy is released as heat during normal
body functions such as digestion and movement.
Energy released as heat helps the body maintain
normal body temperature.
During digestion food molecules are broken down,
which releases the chemical energy stored in the bonds.
Light energy and sound energy are transformed
into electrical energy within an organism enabling
it to sense its environment.
