Answer: Holism
Explanation:
Holism is a theory which suggests that parts of the organism are connected, these cannot function independently but as a part of whole organism. 
This can be understood as organism as whole is greater than the sum of its parts. 
Thus everything about an organism can be understood through the components that is if a person is suffering from brain disease then this may affect the control and coordination of the body this is likely to affect the whole organism.

Answer: Respiration
Explanation: 
Respiration is the process of chemical energy stored in food which occurs through various enzyme controlled reactions. Some of the energy generated is stored as adenosine triphosphate (ATP) Hence, chemical energy from food is converted to chemical energy in the cell which the cell stores as ATP
