What do fleas primarily feed on?

• A. Plants and seeds
• B. Wood and debris
• C. Blood from pets and people
• D. Dry skin cells from humans

Answer: (C)

Fleas primarily feed on blood, which they obtain from their hosts, such as pets (like cats and dogs) and humans. This feeding behavior is crucial for their survival, as fleas require blood to reproduce and develop properly. The adults bite their hosts with specialized mouthparts, extracting blood and causing irritation and discomfort. While other organisms might feed on dry skin cells or debris, fleas have a specific diet that revolves around blood. This choice aligns with the biological and ecological role of fleas as parasitic insects that rely on warm-blooded animals to sustain their lifecycle. Thus, the emphasis on blood consumption highlights the blood-feeding nature of fleas, distinguishing them from other forms of feeding observed in different organisms.
