Question

Your colleague proposes to test the mechanism of ant navigation by placing a food source 7 meters (m) from the nest. she then takes ants from the nest and places them in a spot that is 4 m from the nest and 3 m from the food source. based on the previous data, where do you expect the ants to start searching for their nest on their return trip?

Answer 1

She placed a food source = 7 meters (m) from the nest
she then takes ants from the nest and places them in a spot that is 4 m from the nest and 3 m from the food source

The answer is that the ants are expected to start searching for their nest on their return trip "after they have traveled 3 m from the food source".
