Here's why:

* Biome: A biome is a large-scale community of plants and animals characterized by its climate and the dominant plant life.

* Biotic factors: These are the living components of an ecosystem, such as plants, animals, fungi, bacteria, and protists.

* Abiotic factors: These are the non-living components of an ecosystem, such as temperature, sunlight, water, soil, and air.

In summary, biotic factors are essential parts of a biome, as they interact with each other and with the abiotic factors to create the unique characteristics of that biome.
