Answer:
It can significantly alter the homeostasis of the ecosystem
Explanation:
The trophic level is the position that occupies a given organism/ population/species in the food web. In a food web, the trophic levels are organized into a first category (formed by primary producers, e.g., plants), a second level (primary consumers, e.g., herbivores), and subsequent categories (predators, e.g., carnivores). The abrupt change in the number of organisms belonging to the same trophic level generally has a negative effect on the ecosystem by modifying the trophic structure of communities. For example, decreasing the number of producers will produce a decrease in the number of primary consumers, thereby altering the homeostasis (equilibrium) of the entire ecosystem. On some occasions, it may eventually lead to the extinction of populations and species.
