Answer:
In an ecosystem without herbivores, the trophic dynamics would be affected. Herbivores play a crucial role in consuming plants, which are typically primary producers at the lowest trophic level. Without herbivores, plant populations could potentially grow unchecked, altering the balance of the ecosystem. This could lead to changes in the populations of predators and carnivores, as their prey availability would be affected. Additionally, the absence of herbivores might impact nutrient cycling and energy flow within the ecosystem, potentially leading to unforeseen consequences.
