Textbook Question
Chapter 38, Problem 5A
You decide to plant a garden with a beautiful black walnut tree at one end and a majestic white oak at the other end. You are quite disappointed, however, when none of the seeds you plant around the walnut tree grow. What might explain this observation?
a. The walnut tree filters out too much light, so the seeds fail to germinate.
b. The roots of the walnut tree deplete all of the nutrients from the soil, so the new seedlings starve.
c. The walnut tree produces chemical toxins that prevent seed germination.
