The most reasonable statement about the biotic factors of the biomes is that they are living organisms that interact with each other and with the abiotic factors of their environment to form complex ecosystems. Biotic factors include plants, animals, fungi, and microorganisms, and they play important roles in nutrient cycling, energy flow, and the maintenance of ecological balance. The distribution and abundance of biotic factors are influenced by factors such as climate, soil type, and topography, and they vary widely across different biomes.
