Paragraf tamamlamaSoru #8434
Complete the paragraph with the most appropriate option:
Corals may resemble vibrant sea plants, but they are actually colonies of tiny marine invertebrates known as polyps. These polyps live in an obligate mutualistic relationship with microscopic algae called zooxanthellae. ---- In exchange, the polyps supply the algae with carbon dioxide, shelter, and nutrient-rich metabolic waste compounds, enabling both organisms to flourish in nutrient-poor tropical seas.

- A)Ocean acidification weakens the calcium carbonate skeletons secreted by coral polyps.
- B)Through photosynthesis, the algae produce organic compounds that furnish up to 90 percent of the host's energy needs.
- C)Rising sea temperatures cause corals to expel their algae, leading to widespread bleaching events.

Doğru cevap: B) Through photosynthesis, the algae produce organic compounds that furnish up to 90 percent of the host's energy needs.
Çözüm: Boşluktan sonra "In exchange, the polyps supply the algae with..." (Bunun karşılığında polipler alglere barınak ve karbondioksit sağlar) ifadesi, boşlukta alglerin poliplere ne sağladığının belirtilmesini gerektirir. B seçeneğinde alglerin fotosentezle enerjinin %90'ını sağladığı açıkça yer alır.
