Question

Ants locate sucrose by (a) using a strong sense of smell (b) using a keen sense of vision (c) physical contact with sucrose (d) sensing the particular wavelength of light emitted/reflected by sucrose Select the correct answer from above options

Answer 1

Answer is : (c) physical contact with sucrose Ants locate sucrose by physical contact with sucrose. Ants can smell food using their antennae, which can detect minute odours. But sugars actually do not have a smell. Therefore, when the scout worker ants locate sugar while foraging, they take a piece back home to the colony, while doing this, the ant will leave a chemical trial which the other ants can follow.
