The correct answer is "effect each other" because abiotic factors, such as temperature, sunlight, and soil composition, can directly impact the distribution and behavior of biotic factors, such as plants and animals. Similarly, biotic factors, such as predation and competition for resources, can influence the abundance and diversity of abiotic factors. Therefore, there is a mutual relationship between abiotic and biotic factors in an ecosystem, where they interact and influence each other's existence and functioning.
