What are the abiotic factors that help characterize a biome?

Abiotic factors that help characterize a biome include climate conditions such as temperature and precipitation, soil type, and the availability of sunlight. These elements influence the types of vegetation and animal life that can thrive in a particular area. For example, deserts have low precipitation and extreme temperatures, while tropical rainforests are characterized by high humidity and abundant rainfall. Together, these abiotic factors shape the unique ecosystems found within each biome.
