Final answer:
The smallest ant among the pharaoh, thief, and ghost ants is the ghost ant. These ants are extremely small and pale, measuring about 1.3 to 1.5 millimeters in length, and are known for their large colonies. The correct option is 'c) ghost'.
Step-by-step explanation:
The question of which is the smallest ant out of the pharaoh, thief, or ghost ant can be intriguing. Among these, the ghost ant is known for its petite size. Ghost ants are so small and pale that they are almost invisible, thus earning their name. In comparison, pharaoh ants and thief ants are slightly larger, making the ghost ant the correct option for this question.
Typically, an adult ghost ant measures just about 1.3 to 1.5 millimeters in length. These ants have a characteristic dark head and pale, almost translucent legs and abdomen. Despite being one of the smallest ants, ghost ants build large colonies, often with multiple queens, and can be a nuisance in homes due to their affinity for sweet substances.
Ants are a diverse group of insects and come in various sizes, but when comparing the pharaoh, thief, and ghost ants, it is the ghost ant that stands out in terms of minute size. Thus, if you see a very small, pale ant, there is a good chance it is the ghost ant, making the correct option for the smallest ant 'c) ghost'.
