Answer 1

The most likely impact of reducing low-growing plants from an area on tortoises with two varieties of neck extension ability (short and long distance) would be that:

The proportion of tortoises with the ability to extend their necks a long distance would increase.

This is because, with fewer low-growing plants available for food, tortoises that can reach taller vegetation (i.e., those with longer necks) would have a better chance of survival and reproduction, thereby increasing their proportion in the population. In contrast, tortoises with shorter necks would struggle to find enough food and could be at a greater risk of decline or extinction in that environment.
