c. Describe a fly
A fly is a small, winged insect belonging to the order Diptera. It is known for its characteristic buzzing sound and swift flight. Flies have a slender body with a distinct head, thorax, and abdomen. They possess two large, compound eyes that provide excellent vision and numerous simple eyes called ocelli that detect light and movement.
The body of a fly is covered with tiny hairs, giving it a fuzzy appearance. Its wings are transparent and membranous, allowing the fly to maneuver quickly in the air. On its head, a fly has a pair of short antennae, used for sensing its surroundings and locating food sources.
Flies have a unique feeding mechanism called a proboscis, which is a tube-like structure extending from their mouth. They use it to suck up liquid food like nectar, juices, or even animal fluids. Some flies are known for their ability to regurgitate digestive enzymes onto solid food, which then liquefies, making it easier for them to consume.
Flies play a crucial role in ecosystems as decomposers, feeding on decaying organic matter and waste. However, they can also be considered pests because some species reproduce rapidly and feed on human and animal blood, causing annoyance and potential health risks.
Overall, flies are agile and adaptable insects that thrive in a variety of environments, making them a familiar sight in both urban and rural areas.
