So when one ant meets another, or when it meets a chemical deposited on the ground by another, then it changes direction to follow in the direction of the interaction, and that's how you get the trail of ants sharing your picnic.
Jadi saat semut saling bertemu atau saat ia menemukan jejak semut lain di tanah, ia mengubah arah untuk mengikuti arah interaksi, dan begitulah Anda mendapati barisan semut merubungi piknik Anda.
