Yes, the effects of removing all species from a trophic level will vary depending on the trophic level. If all the producers are gone, there is a potential that the principal consumers would die or migrate, causing the trophic levels to be disrupted. This holds true at all levels. As a result, removing species at any level would disrupt the entire ecosystem since the food chain would be disrupted. The survival of higher-level animals is entirely contingent on the survival of lower-level animals.
