Comparing Hypotheses on Plant Growth

Two scientists, Dr. Green and Dr. Blue, conducted individual studies to examine the impact of sunlight on plant growth. Dr. Green hypothesized that plants exposed to more sunlight would grow taller than those in shaded areas. In contrast, Dr. Blue proposed that while sunlight is crucial, nutrient-rich soil would have a more significant effect on the height of the plants than sunlight alone.

Based on these hypotheses, which scientist's viewpoint emphasizes different aspects of plant growth?
