Question

Observation: Hiking trails with more human foot traffic have less woody vegetation (e.g, trees) than hiking trails with less human traffic.

1. Create a hypothesis to explain the observation.
2. Design an experiment to test this hypothesis.
3. Make a prediction about your result.

Answer 1

The trees live in places where the human foot does not falls.Because the path where the humans walk the trees can not grow properly.

So in the hiking path with more human foot traffic contains less trees than the hiking path with less trees,even the contain of grass is also less in the path where humans walks.

In order to make a experiment we can speread some seeds of fast growing shurbs like bush & grass in the public garden and then we have to observe for few weeks. We will observe that the planted seeds will mature to seedling every where but where the humans walks the seedings will not grow or the grown seedlings will die due to human foot or walking.

So it is the actual problem that the trees on the hiking trails face due to traffic of human foot.
