Macrofauna refers to large animals that are typically visible to the naked eye and can be found in various ecosystems, including terrestrial and aquatic environments. These organisms play crucial roles in their habitats, contributing to nutrient cycling, soil aeration, and the overall health of ecosystems. Examples of macrofauna include mammals, birds, reptiles, and large invertebrates like crabs and earthworms. In ecological studies, macrofauna are often used as indicators of environmental health. Their presence and diversity can reflect the quality of habitats and the impact of human activities. Understanding macrofauna helps scientists assess biodiversity and develop conservation strategies to protect ecosystems and their inhabitants.
