Macrodetritivores are larger organisms such as millipedes, springtails, and woodlouse, while microdetritivores are smaller organisms such as bacteria.[4][5]. 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).

Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. In the wild they can live up to 15 years old. Conserv. Hydropedological insights when considering catchment classification. HHS Vulnerability Disclosure, Help Aust. 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). These shifts led to changes in isotopic divergence, dispersion, evenness, and uniqueness. Giertz, S., Junge, B. & del Castillo, R. F. Soil changes during secondary succession in a tropical montane cloud forest area. 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.

However, deforestation of tropical forest, with a net rate of 5.5 million hectares annually in 20102015, profoundly impacts soil properties and functions. FAO. Sampling took place across a total of 32 sites: 8 sites in each of 4 land-use systems: forest (D), jungle rubber (E), rubber plantations (F), and oil-palm plantations (G). If that carbon gets locked up somewhere then some bird, grasshopper, or bot fly wont be able to eat.
