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?
1. The variety of tortoises that could only extend their necks a short distance would go extinct
2. The proportion of tortoises that could only extend their necks a short distance would increase
3. The proportion of tortoises with the ability to extend their necks a long distance would increase.
4. The variety of tortoises with the ability to extend their necks a long distance would go extinct
3. The proportion of tortoises with the ability to extend their necks a long distance would increase.
Reducing low-growing plants in an area would likely favor tortoises with the ability to extend their necks a long distance, as they would have better access to higher vegetation. This could lead to an increase in the proportion of tortoises with long-distance neck extension ability in the population. On the other hand, tortoises with only short-distance neck extension ability may struggle to reach higher vegetation and could potentially decline in numbers. Overall, the population dynamics of the tortoises would likely shift towards favoring individuals with the long-distance neck extension ability in response to the reduced availability of low-growing plants.
