I want to build some sort of an enclosed ecosystem. It can range from very small to quite large, but im talking about a DIY project so nothing really big. It can be water based, or land, or even both. Thanks!

Its called a terrarium. Fill a 2 liter bottle halfway with soil, plant some small plants in it, add a few insects, then spray with some water and then reseal the bottle. You aren't going to get the ratios perfect, but set out in the sun, the water and air cycle should last for a few days before the insects starve, CO2 is no longer produced, and the plants die. I've done a few of these. My longest one lasted about 4 days, which is pretty good, considering I was probably 10.
