How does a whale-fall community affect ocean sediment? the decomposition of the whale enriches the sediment. the remains of the whale pollute the sediment. the sediment is transformed into food for mussels and crabs. the bacteria that are attracted break down the sediment nearby.

The answer is A. The decomposition of the whale enriches the sediment.

When a whale dies, it falls to the ocean floor. Its dead body is known as whale-fall. This whale-fall provides nutrients for a whale-fall community, which includes bacteria, crabs, worms and other invertebrates. Organic fragments from the whale-fall enrich the sediments nearby. Enrichment opportunists colonize the whalebone and surrounding sediment in order to feed on these organic fragments.

The answer is A
