AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
An ecosystem is the term that describes all the interacting organisms in an area together with the non-living physical factors (abiotic components like temperature, soil, rainfall) of their surroundings.
Source: Chapter 13, Section 13.1 – Ecosystem: What Are Its Components?
