Final answer:
Mineral nutrients in soils have implications for primary productivity in plants. Soil structure, pH, and nutrient content influence the distribution and abundance of plants. Soil provides support, water, heat, nutrients, and oxygen to plants.
Step-by-step explanation:
Mineral nutrients in soils have a significant implication for primary productivity in plants. These essential nutrients, such as nitrogen and phosphorus, are obtained by plants from the soil through their roots. The availability and distribution of these nutrients in the soil, along with factors like soil structure, pH, and nutrient content, play a crucial role in determining the distribution and abundance of plants. Additionally, soil provides physical support, water, heat, nutrients, and oxygen to plants, all of which are necessary for their growth and productivity.
