The deep ocean floor was long presumed to be a biological desert incapable of supporting complex life. In 1977, however, oceanographers exploring the Galápagos Rift made an astonishing discovery: thriving communities of giant tube worms and blind crabs clustered around hydrothermal vents. ----. Instead of relying on solar photosynthesis, chemoautotrophic bacteria oxidized hydrogen sulfide spewing from volcanic fissures to generate organic sustenance.
- A)These bizarre organisms thrived in total darkness through chemosynthesis rather than solar energy
- B)Sunlight penetrates thousands of meters into deep ocean trenches to fuel microscopic algal blooms
- C)Giant tube worms feed exclusively on terrestrial leaves that drift down from continental rivers
- D)Hydrothermal vents were proven to be artificial geothermal wells drilled by naval submarines
- E)Marine biologists immediately concluded that no life could ever exist in oceanic rifts

Doğru cevap: A) These bizarre organisms thrived in total darkness through chemosynthesis rather than solar energy
Çözüm: Sonraki cümlede kemosentez ("chemoautotrophic bacteria oxidized hydrogen sulfide...") anlatılmaktadır. A seçeneğindeki "thrived in total darkness through chemosynthesis..." bu cümleyi kusursuz bağlar. Doğru cevap A'dır.
