Nutrients in the soil aid the process of energy production through photosynthesis.  in this example, between which two spheres is energy exchanged

Geosphere and Biosphere

Explanation:

The geosphere is defined as the region that is comprised of all the rock materials, soil and other particles, existing on or below the earth's surface.

And the biosphere is defined as the region that comprises all the living organisms existing on earth. This includes all the plants, animals and micro-organisms.

According to the given condition, soil is a part of the geosphere and plants are a part of the biosphere, where the soil provides all the necessary nutrients to the plants, that helps in carrying out the process of photosynthesis in the presence of sunlight, water and carbon dioxide. It thus liberates food and oxygen that is essential for all the living organism.

Thus, the energy is exchanged between geosphere and biosphere.

not completely sure but i think it’s many moons, smaller in size and a ring system.
