Community structure refers to the organization and arrangement of different species within a specific area. It includes the variety of species present, their abundance, and how they interact with one another. This structure can be influenced by factors such as environmental conditions, resource availability, and human activities. Understanding community structure is essential for studying ecosystems, as it helps scientists assess biodiversity and ecosystem health. By examining the relationships between species, such as predators, prey, and competitors, researchers can gain insights into how communities function and respond to changes in their environment.
