Answer:
Parasite
Explanation:
Fleas, mosquitoes, and ticks are all examples of parasites. Parasites are organisms that live in or on another organism. Parasites feed off their hosts but harm the host in the process.
Some parasites, such as fleas, mosquitoes, and ticks, feed off the blood of their hosts, and they often move from host to host. Because of this, these parasites can carry and transmit diseases, such as malaria, West Nile virus, and bubonic plague.
