How can ants be differentiated from termites?

1. Ants have straight antennae and broad waists

2. Ants have thin waists and elbowed antennae

3. Ants are always larger than termites

4. Ants build nests while termites do not

The correct answer is: Ants have thin waists and elbowed antennae

Ants can be differentiated from termites primarily through their distinct physical characteristics, with one of the key differences being their antennae and the structure of their bodies. Ants possess elbowed antennae, which create a noticeable bend in the antennae. This feature helps in identifying them quickly as it contrasts sharply with termites, whose antennae are generally straight and less distinct in shape. Additionally, ants have a noticeably thin waist, which sets them apart from termites that have a more robust, wide abdominal region appearing almost uniform in width. These features are crucial for correctly identifying these insects and understanding their behavioral and ecological roles. The other options do present some inaccuracies; for instance, while certain ant species may be larger than some termites, this is not a universal rule and therefore cannot be relied upon for identification. Furthermore, both ants and termites construct nests; this points to a misunderstanding of their behaviors rather than a clear differentiating characteristic.
