Suppose you are tracking a population's size over time, and you observe that the population size varies in a way that appears chaotic. What does this mean about the factors that influence this population's growth?A) The population must be experiencing demographic stochasticity. B) The population must be experiencing environmental stochasticity. C) The population must be experiencing both demographic and environmental stochasticity. D) It is difficult to tell because chaotic population fluctuations can occur even when environmental and demographic conditions do not change.

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.
