Definition
A 'free-living' organism is one that doesn't depend on another organism for survival. It's like a wild animal π that finds its own food and shelter without needing a host. This contrasts with parasites, which rely on a host for nourishment and survival. Free-living organisms can be found in various environments, from soil to water. They obtain their nutrients from their surroundings, independently. Think of it as a plant that gets its nutrients directly from the soil.
