So for anyone who doesn't know, the domino effect is when you take one thing out of something and it affects everything. For instance, when you take a domino out of a line, the entire line of dominos won't go down. We used these dominoes to represent an ecosystem because if you take one thing out of the ecosystem, it would affect everything. For example, if you take away the sun, every living thing in the ecosystem would die. In fact, the entire world would die. You can say the same thing for water. Even if you take away a primary predator, it would affect the ecosystem as there would be an overabundance of a certain animal which could be bad. After doing this project, we feel like we learned more about not only ecosystems but food webs and food chains as well. We learned that the littlest things could have a huge effect on everything. Some things that stood out to us was the fact that some animals that you don't think are important to an ecosystem really are very important. For instance, we didn't think flies were important but if you take out flies, animals like frogs wouldn't be able to eat them which could cause frogs to decrease in population. Then animals like snakes would decrease and it would keep going and going. Something we are still wondering is can there be an ecosystem that isn't affected if we take something out of it.
