Consider two ecosystems that scientists have labelled as ecosystem A and ecosystem B. The scientists have found that both ecosystems are home to a roughly equal number of species. However, ecosystem A is dominated by a small number of species that are very abundant. Ecosystem B, by contrast, has a more even abundance of organisms across its species. From this description, ecosystem B is considered ecosystem A.
