Question

below is a food web from little rock lake, a freshwater lake ecosystem in wisconsin. which one of the following organisms eats a producer in this food web? backswimmer water cricket water flea whirligig beetle

Explanation:

1. First, identify producers in the food web: golden algae and green algae are producers (autotrophs that make their own food).
2. Check each option's food source:

• Backswimmer: Eats golden algae (a producer)
• Water cricket: Eats water mold, not a producer
• Water flea: Eats rotifer/copepod, not producers
• Whirligig beetle: Eats green algae? No, the arrow shows green algae is eaten by rotifer; whirligig beetle is prey for black crappie, no arrow from producer to it.

Answer:

backswimmer
