What will happen if we kill all the organisms in one trophic level?
Tropic levels in the food chain are interlinked with one to another level in the sequential manner. If we kill all the organisms in one trophic level, the flow of energy at each tropic level is reduced 10 percent and the food chain get disturbed that creates an imbalance in the ecosystem.
For example, food chain is:- crops ← Rats ← Owls
In this food chain, crops are eaten by rats and then rats are eaten by owl population. If all the owls in the one trophic level get killed, there will be increase in the rats population and will lead to the overeating of the crops will happen. And, due to the overeating can lead to barren land which will affect the another trophic levels due to the soil erosion. So, as a result if we kill one trophic level, the lower trophic level will reproduce and population will get increases that disturbs the ecosystem.
