Can somebody give me description of the role of these decomposers i'm going to list below: - spiders

- freshwater shrimps

-moss

they break down organic material that then provide nutrients for the entire food web.

- freshwater shrimps

Animals like shrimp and crabs can break the materials down to detritus. Then bacteria reduce the detritus to nutrients.

-moss

Moss is considered both a producer and a decomposer because it produces its own food through photosynthesis and helps to break down organic matter into nutrients. ...
