Final answer:
The distribution of solar radiation plays a crucial role in determining the distribution of organisms because it affects the growth of photosynthetic organisms, which in turn affects the distribution of herbivores and predators that rely on them for food.
Step-by-step explanation:
The distribution of solar radiation plays a crucial role in determining the distribution of organisms. In terrestrial habitats, the intensity and duration of sunlight vary, resulting in different light availability at different locations. This variation in light availability affects the growth of photosynthetic organisms, which in turn affects the distribution of herbivores and predators that rely on them for food. In aquatic environments, light intensity is influenced by factors such as water depth and transparency, which also impact the distribution of photosynthetic organisms and the organisms that depend on them for energy.
