Paragraph to Complete:

```
__________ is the process by which plants produce their own food in the presence of __________, __________, and __________. Photosynthesis occurs in the organelle called __________ that's only found in plants. Plants contain a green pigment called __________ that absorbs sunlight. Energy from the sun, carbon dioxide from the atmosphere, and water absorbed by the roots react to produce __________ that plants need to survive. __________ is a gas that is released into the environment for animals and humans to breathe.
```
