You are on a town committee formed to determine the borders for a new local nature park. You explain that according to the theory of island biogeography, if the committee wishes to promote species richness it should

Giant tube worms live on the ocean floor near hydrothermal vents. This environment experiences temperatures far hotter than most organisms can withstand and contains a high concentration of toxic chemicals such as hydrogen sulfide that escape from the vents. Which of the following statements best explains why the giant tube worm can survive in this environment?
A. Competitors of the giant tube worm were wiped out by pollution, allowing the worms to dominate the ecosystem
B. The toxic environment near the vents led to a trophic cascade that eliminated tube worm predators
C. Giant tube worms are well adapted to the environment near the vents and can thrive there outside the range of tolerance of other organisms
D. Giant tube worms can survive in any environment, so it makes sense that they would fill an available niche
What is C?
