Answer 1

To assess the impact of reducing low-growing plants on a population of tortoises with different neck extension abilities, consider the following:

If low-growing plants are reduced, food availability for the tortoises that can only reach those plants (i.e., the short-necked tortoises) will be compromised. This would likely lead to increased competition for food resources among the tortoises. As a result, the short-necked tortoises may struggle to find sufficient food, potentially leading to a decrease in their population.

On the other hand, tortoises with the ability to extend their necks a long distance may still be able to find food by reaching taller vegetation or plants that are less affected. Consequently, over time, the proportion of long-necked tortoises may increase, as they have better access to food resources and may have a higher survival rate.

Therefore, the more accurate response is:

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