Which pair of organisms can be in a parasite/host relationship?
Examples of pairs of organisms that can be in a parasite/host relationship include:
1. Fleas and dogs: Fleas are parasites that infest the skin of dogs, feeding on their blood.
2. Mosquitoes and humans: Mosquitoes transmit parasites, such as the Plasmodium parasite that causes malaria, to humans when they bite and feed on their blood.
3. Ticks and mammals: Ticks are ectoparasites that attach themselves to a variety of hosts, including mammals like deer, dogs, and humans, to feed on their blood.
4. Tapeworms and humans: Tapeworms are internal parasites that can infest the intestines of humans, absorbing nutrients from the host's digestive tract.
5. Lice and humans: Head lice and body lice are parasites that infest humans, feeding on their blood and causing discomfort and itching.
These are just a few examples; there are numerous other parasites that have adapted to exploit various host organisms for their survival and reproduction.
