Parasites attach themselves to host animals mainly for nutrition and shelter. The parasites cannot find their own food and shelter by themselves so they depend on others for this. This habit of parasites may emerge to be harmful for he host body as the parasites draw their nutrition for their own existence.

For many of the same reasons any organism travels. Organisms that travel do so because it is an effective strategy for avoiding predation, leaving regions with unfavorable conditions, entering regions with favorable conditions, finding mates, and finding hosts. A secondary cause of parasite movement is of course that many attach themselves to their hosts and thus travel wherever the host travels, the movements of the host likely dictated by the concerns of predation, food, mating, etc.

Because virus has only one genetic material i.e. DNA or RNA. So it has to depend on host's cell for anyone of the genetic material which it lacks.

How are parasites and predators alike?

Parasites and predators are both organisms that consume other organisms for survival. However, parasites typically live on or inside their host, feeding on its tissues without immediately killing it, while predators actively hunt and kill their prey. Both parasites and predators play important roles in regulating populations in ecosystems.

Study of organisms which derive nourishment and protection from other living organisms?

This is known as parasitology, which is the branch of science that focuses on the study of parasites and their interactions with their host organisms. Parasites are organisms that depend on other living organisms for their survival and reproduction. This field of study is important for understanding the relationship between parasites and their hosts, as well as for developing strategies to control parasitic infections.


Organisms that depend on the food energy stored in other living organisms?
