Final answer:
Diatoms, foraminifers, radiolarians, and coccolithophores are organisms responsible for the creation of siliceous ooze.
Step-by-step explanation:
Siliceous ooze is created by organisms that produce and deposit silica (silicon dioxide) in their exoskeletons or shells. The organisms responsible for the creation of siliceous ooze include diatoms, foraminifers, radiolarians, and coccolithophores. Diatoms are unicellular photosynthetic organisms that produce an external skeleton made of silica dioxide. Foraminifers are unicellular heterotrophic protists that exhibit porous shells built from various organic materials and hardened with calcium carbonate. Radiolarians are another subtype of Rhizaria that exhibit intricate exteriors of glassy silica. Coccolithophores are marine algae organisms that have ornate calcium carbonate plates as their coating.
