The tortoises develop longer necks as an adaptation. They have to be able to reach the grass in order to feast upon.

Answer 2

1. the tortoises will develop longer necks

Step-by-step explanation:

Organisms develop adaptive traits to make themselves better adapted to their surroundings. Evolution of taller grasses on the island would lead to the evolution of long necks in tortoises to prevent them from starving.

The tortoises with a longer neck would be favored by natural selection due to their survival advantage. They will leave more progeny. Gradually, the population would consist of tortoises with a longer neck.
