Question

How would you compare and contrast Parasitism and Predators?

Answer 1

Hint: Nonspecific interactions between two separate organisms in an ecosystem are predation and parasitism. Here, predation and parasitism both harm one species and benefit another.

Complete answer:

	Predation	Parasitism
Definition	The act of one animal preying on another animal.	The activity of living on or within the body of another person as a parasite.
Relationship	Relation is between a predator and a prey	Relation is between a parasite and host organism
Mode of Action	Hunt, kill the prey and attack it.	enter the host cells, live, use resources and to cause damage.
Number of hosts	Interact with several preys	Interact with only one host organism
Size	Larger and stronger than the prey	Smaller than the host organism
Metabolic dependency	There is no such reliance on metabolism between the predator and the prey.	An intimate relationship exists involving the host's metabolic dependence.
Progression	Predation: The predator is very aggressive, using intense physical effort to capture the prey.	Parasitism: The progression of parasites is usually inactive.
Types	Herbivores , Carnivores and Omnivores	Virus , Helminths and ectoparasites
Mode of nutrition	By killing their prey to gain nutrients.	Acquire the host species' nutrients.
Surplus killers	Yes, they are surplus killers, since they kill their prey instantly.	No they're not the surplus attacker, so they're not killing the host organism right away.
Completion of life cycle	There is no such case between the prey and the hunter,	Host is required to complete their life cycle

Note: Other than animals, plants may also be applied to the idea of predation.
Elephants, for example, eat leaves, bears eat berries, and so on.
Tapeworms that are found attached to the animals' intestines prey on the food of the host, depriving it of nutrients. In humans, plants, animals and even in insects, parasitism is also observed. Viruses are the best example of parasites, which by entering their cells, affect all living organisms.
