Which characteristic allows species of the same type to coexist in the same habitat without competition?

Given below are two statements $:$
Statement-$I$ : Species facing competition might evolve mechanisms that promote co-existence rather than exclusion.
Statement-$II$ : In endoparasites,morphological and anatomical features are greatly simplified while emphasising their reproductive potential.
In the light of the above statements,choose the correct answer from the options given below.

Given below are two statements:
Statement-$I$: For plants,herbivores are the predators.
Statement-$II$: Nearly $25\%$ of all insects are known to be phytophagous.
