I just came across a very cool and interesting article about Trophic cascade. Having not really heard the term before I found it fascinating. The thought that one species can change the whole ecology of an area! This is also true in reverse. Introducing a species to an area can decimate an area. There are fish called Asian Carp, which can populate so quickly that it can ruin a body of water killing off other fish populations. The name of the article is called Wolves Introduced to Park Revitalize Eecosystem. Great story! Now I would love to visit Yellowstone! Click on the link above to see the story of the Wolves!
It is so crazy that a fish can destroy an entire ecosystem. This could be a great example for students on how we can be the invaders in different ecosystems. We should observe without removing anything or leaving anything behind.
