Which of the following best describes a biome?

A biome is characterized as a large geographical area defined by distinct climates, flora, and fauna that adapt to those conditions. This broad definition encompasses various ecosystems, such as forests, deserts, and grasslands, each of which is influenced by environmental factors like temperature, precipitation, and soil types. The unique combination of these elements supports specific plant and animal communities, distinguishing one biome from another.

In contrast, the other options refer to narrower concepts. A preserved area of forest pertains to conservation efforts rather than the broader classification of ecosystems. A specific type of tree is too limited, as it does not encompass the variety of organisms and ecological interactions that define a biome. An artificial habitat implies human-created environments, which do not naturally occur in the same way that biomes do. Therefore, the description of a biome as a large geographical area with distinct flora and fauna is the most accurate.
