A. Earthworms are autotrophic.
B. Earthworms are ciliate.
C. Earthworms are saprotrophic.
D. Earthworms are mixotrophic.
Answer (2)
Earthworms are best described as saprotrophic organisms as they obtain energy by feeding on decaying organic matter in the soil. This feeding method allows them to recycle nutrients, which is critical for soil health. By breaking down dead material, earthworms contribute significantly to the ecosystem. ;
