In a study of large mammal species, it was found that these animals require substantial quantities of food to thrive. When environmental conditions worsen, these mammals often struggle to locate sufficient food. This situation increases the risk of extinction for large mammals compared to smaller mammals, which can sustain larger populations with less food. Based on this information, which of the following statements is most supported? (A) The primary factor influencing the extinction risk of an animal species is the maximum population size that can be sustained by the available food. (B) The likelihood of an animal species facing extinction is partly determined by the amount of food its members need to survive. (C) In deteriorating environmental conditions, no small mammal species will go extinct unless a large mammal species also does. (D) The survival chances of any individual within a species are mainly dependent on the food requirements of that individual. (E) When environmental conditions are severe enough to endanger large mammal species, small mammal species can still find adequate food to survive.
