What are the similarities and differences between predation and parasitism?

Predation and parasitism are examples of food relationships between individuals, the similarity is that one organism uses the other (waste products) as food. Differences: predation is a way of obtaining food and nutrition of animals, in which they catch, kill and eat other animals, and parasitism is a way of feeding due to the nutrients of another organism (host), and the latter does not die from this, but feels depressed .

Unlike predation, when attacked by a parasite, the host does not die immediately, but experiences oppression (often for a long time). In other words, the parasite exhausts, but does not destroy the host, because the life of the host ensures its existence. Thus, parasitism can be considered as a weakened form of predation. In nature, there are often such interactions that can be called transitional from predation to parasitism: for example, mosquitoes and leeches, sucking blood from mammals.
