Answer 1

Nutrients primarily come from detritus sinking from more productive shallower water.

Define detritus.

In contrast to dissolved organic material, detritus is dead organic material that is in the form of particles. Detritus typically consists of faces and the carcasses or remains of dead organisms. Communities of microbes that colonize and breakdown (i.e., remineralizer) detritus are frequently found in it. It is known as "soil organic matter" and is present in terrestrial ecosystems as leaf litter and other organic matter that is combined with soil. Organic matter that is suspended in water and accumulates in depositions on a body of water's floor referred to as "marine snow" when the floor is a seabed is referred to as detritus in aquatic ecosystems.
