Which is an abiotic factor that helps determine the characteristics of a biome?

• amount of plant life
• amount of precipitation
• number of animal species
• amount of biodiversity

Amount of precipitation

The abiotic factor that helps determine the characteristics of a biome is the amount of precipitation. To determine the amount of precipitation in a biome, we can look at historical weather data such as rainfall measurements over a specific period of time. This data can be obtained from various sources such as meteorological agencies, scientific research publications, or online databases. By analyzing the precipitation data of a particular region, we can understand its average rainfall patterns, which in turn, helps determine the overall characteristics of the biome, such as the types of vegetation that can grow there, the availability of water resources, and the overall ecosystem dynamics.

The correct answer is the amount of precipitation.
