Question

which organisms are tertiary consumers in this food web? select all that apply.
shiner black crappie
golden algae water cricket

Explanation:

To determine tertiary consumers, we analyze each organism:

• Shiner: In a food web, tertiary consumers eat secondary consumers. If shiner preys on secondary consumers (e.g., small carnivores), it can be a tertiary consumer.
• Black crappie: Often a higher - level predator, consuming organisms that are secondary consumers, so it can be a tertiary consumer.
• Golden algae: Algae are producers (they make their own food via photosynthesis), not consumers, so it is incorrect.
• Water cricket: Usually a primary or secondary consumer (eats producers or primary consumers), not a tertiary consumer, so it is incorrect.

Answer:

A. shiner, B. black crappie
