Question

which organisms are secondary consumers in this food web? select all that apply. golden algae rotifer backswimmer water flea

Explanation:

To determine secondary consumers, we first identify producers (like golden algae, green algae) and primary consumers (organisms that eat producers). Secondary consumers eat primary consumers.

• Golden algae: Producer (makes food via photosynthesis), not a consumer.
• Rotifer: If it eats primary consumers (e.g., organisms that ate algae), it could be a secondary consumer.
• Backswimmer: Likely eats primary consumers (e.g., rotifers or water fleas that ate algae), so secondary consumer.
• Water flea: Often a primary consumer (eats algae), but if the food web shows it eating primary consumers, but in typical aquatic webs, water flea (daphnia) is primary. Wait, but the arrows: Let's re - evaluate. The rotifer's arrows: if rotifer eats primary consumers (like organisms that ate golden/green algae), and backswimmer eats rotifer (a primary or secondary? Wait, maybe the correct secondary consumers here are rotifer (if it eats primary consumers) and backswimmer. Wait, maybe the initial selections were wrong. Wait, golden algae is a producer (autotroph), so not a consumer. So the correct secondary consumers should be rotifer (if it eats primary consumers) and backswimmer. Wait, maybe the intended correct ones are rotifer and backswimmer. Wait, maybe the user's initial checkmarks were incorrect. Let's clarify: Secondary consumers are organisms that consume primary consumers (herbivores or omnivores that ate producers). So:
• Golden algae: Producer → not a consumer.
• Rotifer: If it eats primary consumers (e.g., water flea that ate algae), then secondary.
• Backswimmer: Eats rotifer (a consumer), so secondary.
• Water flea: Primary consumer (eats algae) → not secondary.

So the correct secondary consumers are rotifer and backswimmer. But maybe the problem's context has specific arrows. Assuming the food web has rotifer eating primary consumers and backswimmer eating rotifer, then rotifer (if it's a secondary) and backswimmer. But maybe the initial checkmarks were wrong. Let's re - answer: The secondary consumers are rotifer (if it consumes primary consumers) and backswimmer. So the correct options are rotifer and backswimmer. Wait, maybe the user made a mistake with golden algae (producer) and water flea (primary). So the correct ones are rotifer and backswimmer.

Answer:

rotifer, backswimmer
