Answer:
It wouldn't completely disrupt the system but, it'd make some major changes. Removing a species would be like removing a piece in the game of bricks. More bricks you'd remove the more unstable it'd get. So, I'd say don't remove any species from ANY ecosystem, for the safety of the world. If one ecosystem is disrupted, an entire species could die off. If one dies off, so would another and it'd keep going.
Hope this helped, have a good day!
