Earthworm is an example of ______________feeder?
Correct answer: A. Detritus
- A. Detritus
- B. Fluid
- C. Macrophageus
- D. Filter
Explanation
Earthworms ingest soil and feed on decaying organic matter, called detritus, so they are detritus feeders. A fluid feeder takes liquid nutrients, while a filter feeder strains suspended particles from water; students may choose macrophageus because earthworms ingest relatively large particles, but detritus is the specific feeding category.
