How do these spheres interact lithosphere and biosphere?

Lithosphere and atmosphere: The wind blows dust and sand to new locations and we get new land features. Volcanic eruptions add gases to the atmosphere while changing the lithosphere as well.  

Lithosphere and hydrosphere: Water causes erosion and transport of eroded material and changes the landform. Rivers are a good example of how water erodes land and one of the results (of erosion, transportation and deposition) is the formation of river deltas.  

These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.
