C The variety of tortoises that could only extend their necks a short distance would go extinct.
Reducing low-growing plants from an area would likely decrease the amount of available food for tortoises, especially those with shorter necks that are unable to reach higher vegetation. As a result, the tortoises with longer necks would have an advantage in obtaining food and surviving, while the ones with shorter necks would struggle to survive and eventually go extinct.
How would reducing low-growing plants from an area impact a population of tortoises with two varieties of neck extension ability: short and long distance?
A The variety of tortoises with the ability to extend their necks a long distance would go extinct.
B The proportion of tortoises with the ability to extend their necks a long distance would increase.
C The variety of tortoises that could only extend their necks a short distance would go extinct.
D The proportion of tortoises that could only extend their necks a short distance would increase.
