Question

I need help with these

Answer 1

7) sound energy: crowd cheering, chemical energy: food in the athlete/ crowd, mechanical energy: the movement of the arms and legs of the athlete 
8) chemical to mechanical, this happens in the athlete, the food gets converted to ATP which in turn is converted to mechanical energy.  and the conversion of chemical energy to heat in the metabolic processes of all the people in that photo.  
9) the sunlight travels to earth and into the plant cell to the chloroplasts where photosynthesis takes place carbon dioxide and water are needed for this process.  then the plant has a fresh sugar molecule which it joins with other molecules to form a polysaccharide.  then the humans come along and gather the plant and its parts. then we consume the plant and break down that starch or the sugar.  then we convert the sugars into ATP.  that process puts out metabolic heat and then the cell uses the ATP to do work such as contracting to move a muscle.
