Mosquito Egg-Laying and Blood-Feeding Habits

Steps:

• Recall that mosquitoes require water for egg development, specifically stagnant pools to avoid currents.
• Note that female mosquitoes need blood meals to produce eggs, while males feed on nectar.
• Evaluate choices: Match egg site to stagnant water and blood-sucking to females.
• Select the option aligning with both facts.

Why C is correct:

• Mosquito larvae (wrigglers) hatch in stagnant water bodies, providing necessary moisture and oxygen; females suck blood to obtain protein for egg production, as per insect reproductive biology.

Why the others are wrong:

• A: Eggs are laid on water surfaces, not decaying organic material like soil or compost.
• B: Eggs not in decaying material, and males do not suck blood—they consume plant sugars.
• D: Males do not suck blood; only females do for reproduction.

Final answer: C
