NEET BIOLOGY

Detailed explanation-1: -An interaction between two organisms that benefits one to the detriment of the other is an antagonistic interaction. Predation, herbivory, and parasitism are specific types of antagonistic interactions.

Detailed explanation-2: -Predation is an interaction in which one organism, the predator, eats all or part of the body of another organism, the prey. Herbivory is a form of predation in which the prey organism is a plant. Predator and prey populations affect each other’s dynamics.

Detailed explanation-3: -Parasitism is a kind of symbiosis, a close and persistent long-term biological interaction between a parasite and its host. Unlike saprotrophs, parasites feed on living hosts, though some parasitic fungi, for instance, may continue to feed on hosts they have killed.

Detailed explanation-4: -The term “symbiosis” includes a broad range of species interactions but typically refers to three major types: mutualism, commensalism and parasitism.

Detailed explanation-5: -In a parasitism, two species have a close, lasting interaction that is beneficial to one, the parasite, and harmful to the other, the host (+/-interaction). Some parasites cause familiar human diseases.
