Here's why:
* Diet: Yellow tangs are herbivores, meaning they primarily eat plants (algae).
* Food Source: They consume algae that grows on rocks, coral, and other surfaces in their marine environment.
* Role in the Ecosystem: As herbivores, they play an important role in controlling algae growth, maintaining the balance of the reef ecosystem.
Therefore, since they obtain energy by consuming other organisms (algae), yellow tangs are classified as consumers.
