Explanation
In science, anything abiotic is not alive. Abiotic factors in an ecosystem are things like temperature, ocean currents, and humidity. Abiotic elements play an important role in the world, in a variety of ways. Everything that isn't living, and never was living, is considered abiotic—from the sand on the beach and boulders on a mountain to the sunlight from above and the mineral makeup of the soil beneath your feet. Abiotic comes from the prefix a-, "without," and biotic, "pertaining to life."
