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.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
