Question

Predation and parasitism are which type of interactions
A. (+, +)
B. (+, 0)
C. (-, -)
D. (+, -)

Answer 1

Hint: Predation and parasitism are two interspecific connections that are between two different species of an ecosystem. In predation, the bloodsucker incontinently kills the prey while in parasitism, the sponger doesn't kill the host organism.

Complete step by step solution:
In ecology, a natural commerce is the effect that a brace of organisms living together in a community have on each other. They can be either of the same species( intraspecific relations), or of different species( interspecific relations). These goods may be short- term, like pollination and predation, or long- term; both frequently explosively impact the elaboration of the species involved.
A long- term commerce is called a symbiosis. Symbioses range from mutualism, salutary to both mates, to competition, dangerous to both partners. Interactions can be circular, through interposers similar as participating coffers or common adversaries. This type of relationship can be shown by net effect grounded on individual goods on both organisms arising out of the relationship.
 An commerce between two organisms that benefits one to the detriment of the other is a negative commerce. Predation, herbivory, and parasitism are specific types of negative relations.
 In predation, a member of one species — the bloodsucker — eats part or all of the living, or lately living, body of another organism — the prey. This commerce is salutary for the bloodsucker, but dangerous for the prey (/- commerce).
Parasitism is a type of consumer- resource commerce like predation, but unlike bloodsuckers, spongers don't kill their host and frequently live in or on them for a longer period of time. Some of these associations are largely specific, and therefore, a sponger of one species might not be parasitic to other species.
 Predation and parasitism both are negative relations. In negative commerce, one species is harmed while the other is advantaged.
Option C is the correct answer.



Note:
Predation and parasitism are negative relations as bloodsucker destroys the prey and spongers burglarize their host's nutrition, causing injury leading to reduction in reduplication. The host is a passive organism whereas the parasite is the active one in the parasitism case. In very few occurrences the parasite may sometimes kill the host organism.
