How are photosynthesis and cellular respiration related?
the processes are not related: photosynthesis occurs in plants and cellular respiration occurs in animals
photosynthesis and cellular respiration are part of the same electron transport chain
cellular respiration produces atp, which is used to power the steps of photosynthesis
the sugars produced in photosynthesis are broken down in cellular respiration

Option D, the sugars produced in photosynthesis are broken down in cellular respiration

Explanation:

Photosynthesis and cellular respiration are connected in a way that product of one is used as reactant in the other one. Here, the products of photosynthesis are used in cellular respiration. The glucose and oxygen produced during photosynthesis are used in cellular respiration to produce carbon dioxide and oxygen. Both the processes uses ATP as a source of energy

Hence, option D is correct

answer: 21

step-by-step explanation:

divide 630 by 30. 30 goes into 630 21 times
