Our Environment


What will happen if we kill all the organisms in one trophic level?


The food chain is the series of organisms through which matter and energy are transferred in the form of food from organism to organism. Each step in this series forms a trophic level. Trophic levels are formed on the basis of feeding behaviour. Producers occupy the first trophic level, herbivores or the primary consumers are present at the second trophic level, small carnivores or the secondary consumers are at the third and large carnivores or tertiary consumers form the fourth trophic level.

If we kill all the organisms in one trophic level, the ecological balance will be affected that will end the food chain. For example, if all the herbivores are killed, there will be no food for carnivores and eventually, they will die.
