1) What are the staring materials and products of photosynthesis and cellular respiration?
2) What does the diagram above reveal about the connections between photosynthesis and cellular respiration?

1) Oxygen, sugar, water and carbon dioxide are the main starting material and products of both photosynthesis and cellular respiration.

2) The diagram shows that cellular respiration which requires oxygen and sugar is the opposite of photosynthesis which requires water and carbon dioxide. The products of cellular respiration are the starting materials or photosynthesis and the products of photosynthesis are the starting materials for cellular respiration.

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
