Answer:
Biosphere and Hydrosphere
Explanation:
When a whale dies and sinks to the bottom of the ocean, this is often referred to as Whale fall. At the bottom of the ocean floor, the remaining bone carcasses tend to formulate an intricate localized ecosystem that supports and supplies life forms, in form of various organisms sustenance in the deep ocean. The dead Whale and organisms represents Biosphere, while the Ocean floor represents Hydrosphere.
Hence, in this case, the correct answer is Biosphere and Hydrosphere
