Herbivores - heterotrophs that eat plants Carnivores - heterotrophs that eat herbivores and other carnivores Other feeding modes which may fit into the above categories: Parasites - derive nutrition from other organisms without killing them Scavengers - derive nutrition from dead organisms Suspension feeders - filter small food particles from the water Deposit feeders or detritus feeders - injest sediment and extract small food particles Grazers - scrape food from the substrate Decomposers and Transformers - bacteria which break down organic matter converting it into a form which can be utilized by other organisms (nutrients) The food chain or food web Return to Geology 102 Class Home Page This page created by Pamela J.
