   • The dog is protecting the plant from rain.
   • The plant is using animals to carry its seeds. (right)

2. Luca finds a small plant with spiky seeds stuck to their pants. What might happen next?

   • The seeds stay in one place
   • The seeds are thrown away by wind
   • The seeds go to a new location (right)

3. A burr from a plant sticks to Mei's coat. What happens next?

   • The burr falls off and stays in the same spot.
   • The seeds travel to another place. (right)
   • The burr grows into a new plant right away.

Tip: Plants use burrs or hooks that stick to animals to carry their seeds to new places where they can grow later.
