Technically you are able to argue both ends. Biotic factors are living things while abiotic factors are no living things. since the plant was once living, you can argue that it is a biotic factor, however, I would say the dead plant decay would be abiotic because it is not living anymore. I hope that helped!

Acid rain flows through soils. If the soil part of a watershed, aluminum is released from the soil and into the streams and lakes located in that watershed.
This lowers the pH in the lake from between 6 and 8 (which is the normal pH in lakes and streams) to less than 5.
Both increase of aluminum and lower pH are directly toxic to fish and they kill off fish populations
