Question

1 a texas gulf coast energy pyramid is shown with representative organisms at each trophic level.
which statement best describes the flow of energy through this pyramid?
a the trophic level represented by catfish and gobies receives energy directly from the producers.
b the trophic level represented by shrimp and copepods receives energy directly from the tertiary consumers.
c the trophic level represented by redfish and flounder receives energy directly from the secondary consumers.
d the trophic level represented by wire grass and phytoplankton receives energy directly from the primary consumers.

Explanation:

1. First, identify the trophic levels:

• Producers: Wire grass and phytoplankton (base of pyramid)
• Primary consumers: Shrimp and copepods (eat producers)
• Secondary consumers: Catfish and gobies (eat primary consumers)
• Tertiary consumers: Redfish and flounder (top, eat secondary consumers)

1. Evaluate each option:

• A: Catfish/gobies are secondary consumers; they get energy from shrimp/copepods (primary consumers), not directly from producers. Incorrect.
• B: Shrimp/copepods are primary consumers; they get energy from producers, not tertiary consumers. Incorrect.
• C: Redfish/flounder are tertiary consumers; they get energy directly from catfish/gobies (secondary consumers). Correct.
• D: Wire grass/phytoplankton are producers; they get energy from the sun, not primary consumers. Incorrect.

Answer:

C. The trophic level represented by redfish and flounder receives energy directly from the secondary consumers.
