This is our terrarium, what we used to make it is a goldfish, a snail, spring water, elodea and cosmos. Three changes that have occurred in our terrarium is, after a couple days, the water started to evaporate causing condensation in the inside of the bottle, then, the plant started to sprout and get really tall, lastly, our fish died after a couple days and so did our snail. Our terrarium is similar to an ecosystem, because it has what an ecosystem needs to survive, a form of water, a source of food, and oxygen. it has plant life (elodea and cosmos) and wild life (fish and snail).
