There are many plants that do well with very small amounts of water. You can purchase cacti or succulents in most nurseries and flower shops. If they are already potted in a decorative container in appropriate potting soil, you need only water them occasionally. The frequency and amount of water will depend on the type, number and size of the plant(s) you have purchased and the environment you have them in. Read the card provided for proper maintenance.
There are also decorative "air" plants that require no watering, but do best in a humid environment.
Plants that shrivel and turn brown are not getting enough water. Plants that start showing signs of mold may be overwatered.
None, they get enough moisture fro the plants that they consume.

It will die. And for some plants, too much water can have the same result. Ask your local nurseryman.
It depends on how severe the lack of water or excess of water is. Neither will be healthy and both will eventually die if the situation is severe enough.
This depends on the type of plant you are growing. The obvious answer is enough but that may not help. Err on the dry side if in doubt.
because too much water and not enough other nutrients causes the plants to die.
Like most plants tulips need enough water to survive. Apply water and leave until the soil on the surface is dry then water again. Do not let water lie on the surface.
If you add to much water then the soil will get soggy and mushy so that indecates that the plant overwatered and it is not getting enough sunlight or CO2 and when the soil is dusty dry then the plant is under watered.
no an energy drink is much worse for you than water
Water is one of the much needed ingridients for the process of photosynthesis in plants.
