Abiotic vs. Biotic: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Abiotic refers to non-living environmental factors, while biotic pertains to living organisms in an ecosystem.
Key Differences
Abiotic factors encompass the non-living elements of an ecosystem, such as climate and soil composition, while biotic factors include all living organisms within that ecosystem. Both are essential components that influence the structure and function of ecological communities.

The abiotic components like temperature and water shape the habitat and conditions for life, whereas biotic components like plants and animals interact within their habitats, forming a complex web of life. Each set of factors plays a distinct role in the environment.

Abiotic factors are the stage upon which biotic interactions play out; for instance, sunlight (abiotic) enables plants (biotic) to perform photosynthesis. These biotic entities, in turn, modify their abiotic surroundings, creating a dynamic interplay.

While biotic factors are characterized by growth, reproduction, and metabolic processes, abiotic factors are defined by chemical and physical attributes such as mineral content of the soil or the pH levels of water, which are critical to the survival and growth of biotic forms.

Biotic factors engage in competition, predation, and symbiosis, which are interactions that do not apply to abiotic elements. Conversely, abiotic elements can limit or promote the activities of biotic factors, such as sunlight affecting the growth rates of plants.
