Final answer:
Biomes are primarily determined by climate conditions such as rainfall and temperature, and geographical aspects like latitude, humidity, and elevation. Terrestrial biomes, including the tropical rainforest, chaparral, and taiga, are influenced by these factors which shape their unique ecosystems.
Step-by-step explanation:
The primary factors which determine each biome include climate conditions such as rainfall and temperature, along with geographical aspects like latitude, humidity, and elevation. Terrestrial biomes, which are land-based ecosystems, vary greatly across the Earth and are primarily influenced by these factors. For example, terrestial biomes such as the tropical rainforest, chaparral, and taiga each have distinctive climates that determine their unique plant and animal communities. Temperature and precipitation, including their annual patterns and variations, are key abiotic factors shaping these biomes. In summary, the climate plays a pivotal role in the distribution of biomes and in the biodiversity and adaptations of the organisms inhabiting these terrestrial regions.
