In the case of photosynthesizing organisms such as plants that use photosynthesis, light is very important for their growth. Understory plants of a forest, receive less light, as it is unable to penetrate through higher canopy levels. However, many different plants are adapted to withstand different levels of light, allowing them to survive with less light energy input. As well as light, growth of plants is affected by the availability of the nutrients nitrogen (N), phosphorus (P), potassium (K) and sulfur (S). Each plant needs a specifically balanced ratio of these nutrients in order to survive. Which statement best describes the relationship between light, nutrients, and plants?
