Final answer:
The correct answer is a) Biosphere, hydrosphere, geospheres, and atmosphere, as these are the Earth system parts interacting when Florida's orange trees grow.
Step-by-step explanation:
When Florida's orange trees grow, several parts of the Earth system are interacting. The correct answer to this question is a) Biosphere, hydrosphere, geospheres, and atmosphere. The orange trees are part of the biosphere, which encompasses all living organisms. The growth of these trees depends on water from the hydrosphere, nutrients and support from the soil within the lithosphere (part of the geospheres), and gases such as carbon dioxide and oxygen from the atmosphere.
These spheres work together through various processes, including photosynthesis, where chlorophyll in the trees' leaves absorbs light energy, and the water cycle, which involves the movement of water throughout the hydrosphere, atmosphere, and biosphere.
