Question

below is a food web from a coral reef ecosystem off the coast of the marshall islands, in the pacific ocean. which one of the following organisms eats a producer in this food web? bacteria clam tiger shark manta ray

Explanation:

1. First, identify producers in the food web. Producers are organisms that make their own food, usually plants or phytoplankton (like the phytoplankton and macroalgae here, as they are autotrophs).
2. Then, check the feeding relationships:

• Bacteria: Decomposers, not eating producers directly in the typical food chain sense here.
• Clam: From the food web, clams eat macroalgae (a producer, as macroalgae is a type of autotrophic organism).
• Tiger shark: Top predator, eats other consumers (like manta ray, etc.), not producers.
• Manta ray: Eats zooplankton (which are consumers), not producers directly.

Answer:

clam
