Ques: Q: The interaction of what opposite factors describe a biome and ecosystem? Read this paragraph and choose the correct option from the provided answers: The abiotic factors, such as the amount of rainfall and the temperature, are going to influence other abiotic factors, such as the quality of the soil.
