Zorluk: KolayFunction of Detail in Context

While terrestrial food webs rely primarily on solar energy captured through photosynthesis, deep-sea hydrothermal vent communities depend on chemosynthesis. In these dark benthic environments, specialized bacteria oxidize inorganic compounds, such as hydrogen sulfide, to synthesize carbohydrates. Organisms higher in the trophic web, such as hydrothermal vent crabs, sustain themselves either by grazing directly on bacterial mats or by consuming smaller invertebrates that feed on those mats. Thus, rather than functioning as an exception to general ecological principles, vent ecosystems replicate standard predator-prey dynamics using a non-solar foundational energy source.

Based on the passage, the author's reference to "hydrothermal vent crabs" serves primarily to accomplish which of the following?

  1. A
    Detail the precise feeding behaviors exhibited by a specific marine organism in vent environments
  2. B
    Describe the specialized anatomical adaptations that enable deep-sea predators to hunt in total darkness
  3. Provide an example illustrating how chemosynthetically produced energy flows to higher-level consumersCevap
  4. D
    Demonstrate that chemosynthetic bacteria rely upon decaying benthic crustaceans for essential inorganic compounds
  5. E
    Challenge the claim that deep-sea vent communities follow conventional predator-prey dynamics

Cevap

Provide an example illustrating how chemosynthetically produced energy flows to higher-level consumers
The correct choice identifies that the author mentions hydrothermal vent crabs as a representative example of higher trophic organisms. By explaining that crabs feed on bacterial mats or smaller prey, the author demonstrates how chemosynthetic energy moves from primary producers up the food chain, reinforcing the conclusion that vent systems replicate standard trophic structures.

Adım Adım Çözüm

1
Locate the target detail within the passage and review its immediate context.
The reference to 'hydrothermal vent crabs' appears immediately following the explanation of bacterial chemosynthesis and describes how the crabs feed on bacteria or smaller invertebrates.
Understanding the surrounding sentences is necessary to see how the detail connects to the author's progression of ideas.
2
Analyze the structural role of the detail relative to the overall paragraph argument.
The author uses the crabs as a concrete illustration of organisms higher in the food web obtaining energy generated by chemosynthetic bacteria, supporting the conclusion that vent ecosystems mirror standard trophic structures.
Function questions evaluate the rhetorical purpose of a statement, not just its literal factual content.
3
Evaluate the choices to distinguish the structural function from literal content restatements.
The correct choice accurately identifies the detail as an example of energy flowing from primary producers to higher-level consumers.
Distractors in function questions often restate the literal information or mischaracterize the author's logical trajectory.
