Which best explains what would happen to the muscular system if the digestive system broke down? a. no carbon dioxide would be available to the cells, and the organism would die. b. an increase in wastes would be sent to each cell, and they would become infected. c. oxygen would not be removed, and the muscles would not be able to move. d. no energy would be available to the cells, and the organism would not be able to move.

D. No energy would be available to the cells, and the organism would not be able to move.

Explanation:

Function of digestive system is to breakdown the nutrients into the simpler elements which in turn are absorbed by cells. These simpler elements, such as glucose, amino acids etc,  serve enter the cellular respiration. Cellular respiration is the process of complete oxidation of nutrients to drive ATP synthesis. If digestive system breaks down, processes of digestion of food and cellular respiration would not occur. This would hamper the supply of ATP to muscles and the organism will not be able to move in absence of muscle movement.
