How do mosquitoes use animal blood?

• A. The enzymes and proteins in animal blood are used to produce eggs
• B. To gain energy
• C. To build wings
• D. To digest nectar

Answer: (A)

The main idea is that a female mosquito’s reproductive cycle relies on nutrients from a blood meal. Blood provides high-quality proteins and amino acids that are essential for making yolk proteins. These yolk proteins, stored as vitellogenin, nourish developing eggs in the ovaries. Without this protein-rich meal, egg production is limited or delayed. Daily energy and flight mostly come from nectar sugars, not from blood, so blood isn’t used primarily for energy. Wings are formed during the larval stages, not from an adult blood meal, and nectar digestion relates to sugar intake rather than egg production. So, the proteins in animal blood are used to produce eggs because they supply the building blocks needed for yolk and embryo development.
