Q. 4. What will happen if we kill all the organisms in one trophic level?
If all the organisms of one trophic level are killed, the food chain will become completely imbalanced. The organisms in the immediate higher trophic level will die out due to unavailability of food and the consequences will follow.
Also, the population of the organisms in the immediate lower trophic level will keep on increasing and this in turn will wipe out its immediate lower level due to higher demand but lower supply. Thus the whole food chain will collapse.
If we kill all the organisms in one trophic level the food supply to the next level will stop resulting in imbalance of the ecosystem as a result animals in the higher levels will die making the growth of animals in the lower trophic level increase in an enormous way all of this will affect the overall balance in the ecosystem.
