"Photosynthesis uses the carbon dioxide from cellular respiration to create glucose and oxygen". "Cellular respiration uses the glucose from photosynthesis to create ATP in the mitochondria".
Shows that photosynthesis and cellular respiration are interdependent to each other.
Option (b);
Step-by-step explanation:
Glucose and oxygen are created with the help of sunlight by the process of Photosynthesis. It uses carbon-di-oxide and water for the same. Cellular respiration, on the other hand, consumes this glucose from the above process to convert them into ATP and emits out carbon-di-oxide using oxygen.
Thus, these two process helps to maintain the levels of carbon dioxide and oxygen in the ecosystem. Both the above two systems are depended on each other because one process exhales the same substance where the other process inhales it and balances the ecosystem.
