<u>Answer:</u>
<em>That chemical energy which is not used for cellular work is used to contribute to the entropy of the system. </em>
<u>Explanation:</u>
The <em>chemical energy is stored in the form of sugar in plants and as fats or lipids</em> is used to store energy in animals. The entropy of the system in plant cell is used to produce carbohydrates by <em>combining the water and carbon dioxide. </em>
<em>Humans and animals convert energy obtained from food as fat for the long-term storage of the energy.</em>
Facilitated diffusion and active transport
<span>Facilitated diffusion is the movement of large particles (that cannot otherwise move across the cell membrane) from an area of higher concentration to an area of lower concentration with the help of trans-membrane proteins.</span>
<span>Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration using ATP energy. this may occur with large particles that cannot move across the cell membrane or small ones that can but don't due to the concentration gradient.</span>
<span>A) water, rock, and tectonic cycles</span>
