Difference Between Predation and Parasitism
Predation |
Parasitism |
Definition | |
Predation is an act of preying on one organism to another organism. | Parasitism refers to the practice of living as a parasite on the body of another organism. |
Size | |
They are bigger and stronger than their prey. | The parasite is smaller than the host organism. |
Action | |
Kill, hunt, and attack the prey. | They particularly use the cells of the host, live, cause harm, and use their resources. |
Type of host | |
They interact with different types of prey. | They interact only with one host organism. |
Dependency | |
They don’t have any dependency between both of them. | They have an intimate association involving metabolic dependency on the host organism. |
Nutrition | |
They take nutrients by killing their prey. | They take nutrients from the host organisms. |
Progression | |
In predation predators are active and they use physical efforts to kill their prey. | They invade the living cells and try to utilize the nutrition, therefore, benefiting the other from the host and causing harm to the host. |
Relation | |
It occurs between the predator and the prey. | It occurs between a parasite and a host organism. |
Life Cycle | |
This type of no such event occurs. | Requires host to complete their life cycle. |
Difference Between Predation and Parasitisms
Predation and parasitism are the two different species that interact with each other in an Ecosystem. In between both species, one is been harmed and the other is being benefited. In predation, the stronger one kills and eats the weaker one whereas in parasitism one host causes harm to the other thus one of them getting benefited.
