Answer:
Abiotic factor.
Explanation:
Soil type is an abiotic factor for an earthworm. The soil type helps an earthworm to collect food and increase the population.
Sunlight, soil, water, and rocks are those abiotic factors that contribute to earthworms to obtain their food and to survive under the soil or upper side of the soil.
Like earthworms, many other organisms depend on the abiotic factors for their livelihood.
