Question

a type of symbiosis in which one member of the relationship benefits and the other is harmed is:
a predation
b mutualism
c parasitism
d commensalism
e intraspecific competition
question 27
organisms that obtain their energy from producers or other consumers are:
a autotrophs
b plants
c heterotrophs
d omnitrophs

Explanation:

• First question: Symbiosis where one benefits and the other is harmed is parasitism. Predation is not symbiosis (short-term interaction), mutualism benefits both, commensalism benefits one without harming the other, and intraspecific competition is within a species.
• Second question: Organisms relying on others for energy are heterotrophs. Autotrophs produce their own energy, plants are autotrophs, and "Omnitronhs" is likely a typo (correct term is omnivores, a subset of heterotrophs).

Answer:

First question: C. Parasitism
Second question: C. Heterotrophs
