The impact of removing the organisms of a trophic level is different for different trophic levels. For example, if we remove plants from a food chain, no organism will get food as plants are the primary producers in the food chain. If herbivores are removed from a food chain then carnivores will starve and die and producers are also affected and may die due to competition for space and nutrients. It is not possible to remove a trophic level without causing damage to the ecosystem as they are interlinked.
