looks just right.

And while a scarf the length of a garden hose might not be useful to anyone, those plants [Girl wearing the long scarf at the beach]

in Grandma's garden certainly are.
- 00:36
In fact, plants are important for tons of different reasons. [Coop pointing at a blackboard]
- 00:39
First and foremost, plants are important for food.
- 00:42
Whether it's a giraffe, a cow, a rabbit, or a human that smells like tofu, many animals [Pictures of the animals appearing]

rely solely on vegetation as a source of energy.

- 01:45
They're perfect! [Wood fire]
- 01:46
