Question

which selection identifies a survival challenge all organisms face?
reproducing
climbing
habitat destruction
pollution

Explanation:

Reproducing is a fundamental requirement for all organisms to ensure the continuation of their species; without successful reproduction, a species will go extinct. Climbing is only relevant to certain organisms, not all. Habitat destruction and pollution are human-caused or environmental stressors that do not impact every organism (e.g., some extremophiles are unaffected by typical pollution/habitat loss).

Answer:

reproducing
