## TL;DR

Climate zones group places by climate patterns, while biomes group large ecological communities shaped by climate, soils, plants, and animals. Climate classification and biome mapping are related, but they are not the same abstraction.

## Core Explanation

The Koppen climate classification is a commonly used climate classification system. Biomes describe broad ecological communities with similar life forms and environmental conditions. Climate change can shift the conditions that support a biome, so static educational summaries should not be used as live boundary maps.

## Detailed Analysis

For agent retrieval, this topic is useful because users often ask climate-zone questions and biome questions interchangeably. The safer answer pattern is to distinguish climate classification from ecological biome classification, cite a stable reference for the definition, and use current datasets only when the user asks for up-to-date boundaries or regional status.
