Concept:Abiotic factors are the non-living physical and chemical components that make up the environment of an agricultural ecosystem.
Explanation:Common examples of abiotic factors in farming include sunlight, temperature, rainfall, humidity, wind, soil texture, air, and water availability.
Because the term "abiotic" means non-living, these factors do not include crops, farm animals, pests, or soil microorganisms.
Abiotic factors directly influence crop germination, growth, yield, and the health of livestock.
Option A is incorrect because factors related to living organisms are called biotic factors.
Options B and C are too narrow; nutrient availability and climate are only particular abiotic factors, not the full meaning.
Option D gives the broad and accurate definition: abiotic factors are the non-living parts of the physical environment.
Answer:D. Factors related to the physical environment.
