Q. An ant can see the objects all around it due to the presence of ____:
Answer: Compound eyes
Notes: Compound eyes are found among the arthropods and are composed of many simple eye sets called ommatids. These may give either a single pixelated image or multiple images, per eye. Each sensor has its own lens and photosensitive cells. Some eyes have up to 28,000 such sensors, which are arranged hexagonally give a full 360° field of vision. Compound eyes are very sensitive to motion. With each eye viewing a different thing, a fused image from all the eyes is produced in the brain, providing very different, high resolution images.
