How to Categorize Abiotic Factors in an Ecosystem
There are three types of abiotic factors scientists use to help categorize all the abiotic factors in a given ecosystem. The three types are edaphic, climatic, and social abiotic factors. Edaphic abiotic factors include the layout of the terrain and land, the basic material and state of said material, and any other special land types and formations in a given ecosystem. Climatic abiotic factors refer to the basic temperature, the weather, the strength of the wind, and other climatic-related factors in a given ecosystem. Lastly, social abiotic factors include the availability of water and land, and how said water and land are used in the given ecosystem.
1. Create a Table that has the Three Types of Abiotic Factors

FAQs
Biotic vs. Abiotic factors; what are the differences between biotic and abiotic factors?
Biotic factors are all living organisms in a specific ecosystem. These include all the plants, bacteria, fungi, and animals in a given ecosystem. Abiotic factors are described as all the non-living things in a given ecosystem. Examples of abiotic factors include soil, loam, dirt, sunlight, water, and air. Biotic factors require the utilization of abiotic factors to survive, but the opposite is not true as abiotic factors don’t require abiotic factors. Not only that but biotic factors can adapt to the changes in the environment, whilst abiotic factors cannot adapt to any changes in the environment.
