Our Environment — Question 5

Yes, the impact of removing all the organisms in a trophic level will be different for different trophic levels.

1. Primary Producers (Plants) — Removing plants will cause the collapse of the entire food chain as without photosynthesis the energy input into the ecosystem would stop.
2. Primary Consumers (Herbivores) — Removing all herbivores would result in a surge in plant population. Also, carnivores that rely on herbivores as a food source would face a shortage of prey and ultimately die of starvation.
3. Secondary Consumers (Carnivores) — Removing all carnivores would result in a surge in herbivores population leading to overgrazing and potential damage to plant population.

No, the organisms of any trophic level cannot be removed without causing any damage to the ecosystem.
