Step 1:
To solve this problem, I'll carefully analyze the food web and determine which organisms are tertiary consumers.

Step 2:
: Understanding Trophic Levels

- Primary producers are at the bottom of the food web (plants, algae) - Primary consumers eat primary producers - Secondary consumers eat primary consumers - Tertiary consumers eat secondary consumers

Step 3:
: Identifying Tertiary Consumers

Tertiary consumers are predators at the top of the food chain that eat secondary consumers.

Step 4:
: Analyzing the Options

- Convict tang: Likely a primary consumer (herbivore) - Clam: Likely a primary consumer (filter feeder) - Tiger shark: Top predator, eats other consumers - Triggerfish: Likely a secondary consumer - Manta ray: Likely a secondary consumer

Step 5:
: Selecting Tertiary Consumers

The tiger shark is the only organism in this list that is a tertiary consumer, as it is a top predator that consumes other consumers.

Final Answer

Tiger shark is the only tertiary consumer in this list.
