What is the best way to define the word biome

A biome is a specific environment that's home to living things suited for that place and climate. A desert biome is great for a lizard, but a koala needs the leafy greens of a forest biome.

A biome can be simply defined as a community of plants and animals that have some common characteristics for the environment they exist in.

Explanation:

Biomes are distinct; they are biological communities. These communities have been formed as a response to the climatic conditions that they share. But biome is not to be confused with habitat. Biome is a much broader term, for instance a biome can have a variety of habitats.
