Invertebrate communities refer to groups of organisms without a backbone or spinal column that live together in a particular habitat. These communities play vital roles in ecosystem functioning, such as nutrient cycling, decomposition, and predator-prey interactions. Invertebrates make up the majority of animal species on Earth and can be found in various environments, including freshwater, marine, and terrestrial ecosystems. Studying invertebrate communities can provide valuable insights into biodiversity, ecological relationships, and the impacts of environmental disturbances on ecosystems. Researchers often use techniques such as sampling, taxonomy, and statistical analysis to study invertebrate communities and their dynamics over time.
