Question

a) How do mosquitoes carry disease-causing micro-organisms and spread diseases?

Answer 1

• Mosquitoes act as carriers of disease-causing microorganisms and spread diseases from one person to another. They carry disease-causing microorganisms inside its body.
• For example: The female Anopheles mosquito is a carrier of malarial parasites. When it bites a person suffering from malaria, it sucks the blood of that person which contains the malarial parasite microbes. When this infected mosquito bites a healthy person it transfers the microbes into his blood. So, the healthy person also gets the malarial disease.
