Are all non-living things abiotic? We are trying to figure out if abiotic factors are things that are only naturally occurring, or if they can be man-made? For example, if there is plastic (trash/pollution) in an ecosystem, is it considered an abiotic factor because it could have a impact on the living things?
Question Date: 2017-10-16
Answer 1:

Abiotic means something that does not contain biological material or living things . A chemical like salt is abiotic. Plastic is abiotic because it is not living. Abiotic things can and do impact living things. Sunlight is abiotic but as you know it has a large impact on living things. Another example is, as you mentioned, the chemicals in the air from pollution that can impact living things.
