Competition negatively affects both species as they compete for the same limited resources.
Ref: NCERT Class 12 Biology Chapter 11: Organisms and Populations Population Interactions - Parasitism and Commensalism
Type III survivorship curves are seen in species like frogs, which produce many offspring with high mortality at early stages.
