The geosphere is one of the parts of the earth, which includes the outer part of the earth crust and area above the mantle. The biosphere is the part of earth, which includes all the living beings such as plants, animals, birds and others.
According to the given situation, the soil being the part of geosphere exhibit nutrients which are absorbed by the plants which helps them to grow, survive and facilitates the process of photosynthesis. The plants are the part of biosphere. Therefore, this soil-plant interaction can be define as geosphere-biosphere interaction, exchange of matter and energy between the two spheres.
