What is one example of a PARASITIC relationship given

One example of a parasitic relationship is the relationship between ticks and mammals. Ticks are ectoparasites that feed on the blood of mammals, such as deer, dogs, and humans. The tick attaches itself to the host's skin using specialized mouthparts and feeds on their blood for sustenance. In the process, ticks can transmit diseases, such as Lyme disease, to their host.
