Ecosystems-How we depend on eachother

Hello!!!!As you know,this is my first blog and I'm going to spend it babbling about my ecosystem and all the little critters inside it.When we first started the experiment,I thought we'd have to bring our own jars and do it the old-fashioned way by scooping dirt into the jars and gathering bugs from outside.I was WAAAAY off when I thought that.We got 2-liter bottles and cut the tops and bottoms off and stuck them together.The bottom was an aquarium with algae,elodea,duckweed,our 2 snails,Bonnie and Clyde,gravel,water,and our 2 fish,Small Fry and BigMac.The top was a terrarium with our 2 crickets,2 rolley-pollies,soil,dirt,mustard seeds (That's right,mustard comes from a plant!),grass seeds,alfalfa seeds,and grass,leaf,and twig matter.I'm most excited to see if BigMac (Girl fish)will have babies.I think that when ecosystems say that we depend on eachother,they really mean it!Lets say that there is a lion,a monkey,a gazelle,grass,and bugs.If the lions didn't eat the gazelles and the monkeys,there would be more of them and they would eat all the bugs,so the grass wouldn't be so healthy
