Analogy
Pathogens is like a living system solving a small survival problem: each part has a job, and the answer depends on how those jobs connect.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Learn it
Pathogens are microorganisms that cause disease.
Bacteria, viruses, fungi and protists can all be pathogens.
Viruses reproduce inside host cells and can damage tissues.
