Afish tank could be considered a simple ecosystem. explain why it would be given this classification and what biotic and abiotic factors are present in the fish tank

I kind of know this because I have a fish tank myself. A tank can consist of decor and stones which are the abiotic factors. Bacteria (biotic) grows on these decorations and stones (good and bad) which affect the quality of water they live in, and there are the fish who are affected by the bacteria (biotic). Hope this helps. (if it does, please rate 5 stars)
