Morphology

biologic + defense

The noun phrase is compositionally built from 'biological' (relating to life/organisms) + 'defense' (protection), so the sense of protection against biological threats is directly derivable from the parts. This adjective+noun pattern is a transparent, cross-linguistic construction and a B1 learner who knows both constituents would readily infer the intended meaning, though specific technical nuances may need context.

Etymology

Biological defense is a term made of biological (living things like bacteria or viruses) and defense (actions to protect). Imagine shields stopping tiny, invisible enemies, and that is why the phrase means 'steps to protect people and places from attacks or threats using bacteria, viruses, or poisons'.
