Biotic systems

Posted by Andrew Bone Tuesday, 13th September 2016

Thank you for asking for clarity on this issue: I can understand how it can be confusing at first glance!

Biotic means 'related to life': in an ecosystem, there are living and dead organisms, and material which derives from a once-living organism, or is a product of organisms. So, biotic is broader than 'living', and distinguishes between life-related 'non-living' (tree bark, resin, eggshells, humus) and other 'non-living' components (stones, sand, water) of an ecosystem.

Abiotic is therefore all non-living components which are not part of living organisms, but when we talk of 'abiotic' we would also include factors such as climate, carbon dioxide, mineral ions, sunlight, and soil.
