PTE Vocabulary B2- 16

Task 1

Transcript for Task 1: The weird movements of certain marine species fascinate biologists studying them in captivity. Their survival often hinges on replicating natural habitats in controlled environments, like an aquarium, where oxygen levels are closely monitored. Such research provides valuable insights into the complex core biological systems of these creatures, enabling conservationists to protect their delicate ecosystems in the wild.

Task 2

Transcript for Task 2: A fragile infant sea turtle, born with a soft jaw, was discovered in its natural habitat. Biologists noted an inadequate oxygen supply in the water, which affected its growth. This single organism illustrates the challenges marine life faces due to environmental changes, emphasizing the need for global efforts to protect vulnerable species from extinction.

Task 3

Transcript for Task 3: The unique aspect of coral reefs lies in their intricate microbe ecosystems, which support countless marine organisms. However, rising water temperatures and pollution constrain these ecosystems, threatening biodiversity. Conservationists have made repeated attempts to restore damaged reefs by transplanting healthy corals, but sustaining these efforts requires addressing the environmental challenges at their core.

Task 4

Transcript for Task 4: The spine structure of some deep-sea fish enables them to survive extreme depths. Their fragile skull adapts to high pressure, but bringing them to an aquarium often results in injury. These species demonstrate the complex interplay between anatomy and habitat, underscoring the importance of studying them without causing harm or disrupting their natural ecosystems.
