These organisms in turn feed fish and shrimp, which support wading birds, pelicans, and the endangered Crocodile. Insects, like ants and beetles, will shred most of the leafy matter into tiny pieces with the help of protozoans and little crustaceans called amphipods. Decomposers Provide Nutrients While producers tend to get a lot of credit for propping up ecosystems, mangrove forests wouldn't be able to operate without decomposers. How do they do it?

Detritivores (also known as detrivores, detritophages, detritus feeders, or detritus eaters) are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as feces ).

Knee roots are a type of horizontal root that periodically grow vertically and then, in a near hairpin loop, grow back downsimilar to the look of a bent knee. /Resources << Even without glasses, females of this species keep a sharp eye out for their young. As such, mangroves are receiving growing attention in the climate change debate in relation to their capacity for so-called "blue carbon" sequestration.
