Question

question 6
mosquitoes that spread diseases, such as malaria, are known as
pathogens
protozoa
hazards
vectors

Explanation:

• Pathogens: These are disease - causing agents like bacteria, viruses, etc. Mosquitoes themselves are not pathogens; they carry pathogens (e.g., Plasmodium for malaria).
• Protozoa: This is a group of single - celled organisms. Plasmodium (the causative agent of malaria) is a protozoan, but mosquitoes are not protozoa.
• Hazards: A hazard is a source of potential damage or harm. While mosquitoes can be a hazard due to disease - spreading, the specific term for disease - spreading organisms (like mosquitoes) is not "hazards".
• Vectors: A vector is an organism that does not cause disease itself but spreads infection by conveying pathogens from one host to another. Mosquitoes that spread malaria (by carrying Plasmodium) are vectors.

Answer:

Vectors
