Which of the following is an Abiotic characteristic?
What species of bug are found on a plant

Answer 1

Any process that cycles nitrogen through any ecosystem should qualify, so nitrogen fixation (incorporation into living tissues), nitrification of parts of the system and denitrification of others should all appy.

The definition of producer is that they synthesize organic materials from inorganic materials, that is they get molecules that were part of the nonliving world into living tissues and the major process through which this occurs is photosynthesis.

Abiotic is anything that isn't living. There is only one choice that doesn't involve any living organisms.
