In benthic marine ecosystems, certain deep-sea glass sponges construct intricate skeletal frameworks made of silica. While most filter-feeding organisms in shallow waters rely on turbulent currents generated by surface winds to supply organic particulate matter, glass sponges inhabit abyssal zones where ambient water currents are exceptionally weak. To compensate, the physical geometry of a glass sponge's lattice structure passively modifies the sluggish ambient fluid flow, accelerating water through the sponge's internal cavity and allowing it to filter nutrients without expending metabolic energy on active pumping.
The passage provides the strongest support for which of the following statements regarding glass sponges?
- AThey inhabit abyssal zones primarily because the absence of turbulent surface currents prevents structural damage to their silica frameworks.
- They are capable of acquiring nutrient particles from water without relying on metabolic energy to pump fluid internally.Cevap
- CThey require a significantly higher concentration of organic matter to survive than shallow-water filter feeders require.
- DTheir physical lattice structures alter abyssal water dynamics by generating surface-level turbulent currents.
- EThey consume more metabolic energy during skeletal framework construction than shallow-water organisms consume during feeding.
Cevap
Glass sponges are capable of acquiring nutrient particles from water without relying on metabolic energy to pump fluid internally.
The passage explicitly concludes that the structural geometry of the glass sponge accelerates ambient water through its internal cavity, enabling nutrient filtration without requiring metabolic energy for active pumping. The correct answer is a direct, accurate paraphrase of this textual fact.
