I would say yes it would be ok not to put anything at the bottom of the aquarium. Gravel, stone and plastics are usually used for appearance. If it is a freshwater aquarium and if you plan on using live plants then gravel is necessary.If it is a salt water aquarium then it is necessary to use live rock and live stone.
what type of plants lives in the terrestrial ecosystem?
Plastic plants may look OK but they will not be helping the balance of things in your aquarium. Live plants will use up impurities like Nitrates and will also add Oxygen to the water. Live plants are definitely the way to go.
