Photosynthesis and cellular respiration are dependent on each other. Explain how these two processes are involved when a mouse eats a piece of corn. In your answer, you should explain the inputs and outputs of each reaction, and where they come from or go in this example.

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
