Not only that but they take their job seriously. Macrodetritivores are larger organisms such as millipedes, springtails, and woodlouse, while microdetritivores are smaller organisms such as bacteria.[4][5]. They should be distinguished from other decomposers, such as many species of bacteria, fungi and protists, which are unable to ingest discrete lumps of matter, but instead live by absorbing and metabolizing on a molecular scale (saprotrophic nutrition). In captivity they can live up to 23 years old. E.V. Herbivore and detritivore effects on rainforest plant - PubMed Detritivores are an important aspect of many ecosystems. Biotropica 52, 2233 (2020).

Dashed lines represent consumer absence, and solid lines indicate consumer presence. This study demonstrates that disturbance alters the effects of rainforest consumers, and, furthermore, that consumer activity has the potential to change rainforest successional processes. 13, 555559 (2020).

On each research site, we collected the leaf litter on three square-meters of ground and dumped it onto a sieve (H). Consumer effects on rainforest primary production are often considered negligible because herbivores and macrodetritivores usually consume a small fraction of annual plant and litter production, even though consumers are known to have effects on plant production and composition in nontropical systems.

Reforestation reverses many of the effects of deforestation, mainly in the topsoil, but such restoration can take decades and the resulting soil properties still deviate from those under natural forests. Endemic to the Atherton Tableland region and the largest tropical trees in the world, bull kauri trees (agathis microstachya) grow up to 45 metres tall and have flaky bark and high branches. 69, 906914 (2005). The causes of land-use and land-cover change: moving beyond the myths. Biotic factors in any ecosystem are classified as producers (autotrophs), consumers (heterotrophs) and decomposers (detritivores). Detritivores are there, and they do their job supremely well. Consumer effects on biomass of each plant species in light gaps over time., Treatment effects on total plant aboveground biomass (percent change between treatment biomass and, MeSH 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). USA 115, 32613266 (2018). Young plants could not grow because the soil would be too leafy and not soily enough. Paul, S., Flessa, H., Veldkamp, E. & Lpez-Ulloa, M. Stabilization of recent soil carbon in the humid tropics following land use changes: evidence from aggregate fractionation and stable isotope analyses. The great majority of these nutrients are found in the top one or two inches of soil on the rainforest floor. 49, 84438462 (2013). The image above shows the Ulva Island rainforest in New Zealand.
