• Catch in the wind and the wind carry it to a new place.

• Attach to the fur of animals elsewhere.

• Be eaten or carried by a bird.

Observe the picture below. Some plants have sharp burrs attached to their seeds that help to move the seeds to other areas. Which is MOST LIKELY the way this plant's seeds will travel to form a new plant elsewhere?

• The seeds will get stepped on by people walking on them and carried somewhere else.

• The seeds get eaten or carried by birds and scattered somewhere else.

• The seeds attach to the fur of animals and drop elsewhere.
