Answer 2

The correct answer is: The Food Chain will collapse.

Explanation:

• Trophic level of an organism can be defined as the energy level which an organism occupies in the food chain.
• Killing all the organisms at different trophic levels can have the following impact:

1. At producer level - The entire food chain will collapse as the primary consumers, secondary consumers, tertiary consumers, Scavengers and Decomposers are dependent directly or indirectly on the producers for food and energy.
2. At primary consumer level - This would cause the death of the secondary and tertiary consumers followed by death of scavengers and decomposers which are dependent on the primary consumers for food.
3. At secondary consumer level -This would cause the death of tertiary consumers followed by death of scavengers and decomposers which are dependent on the secondary consumers for food.
4. At tertiary consumer level -This would cause the death of scavengers and decomposers which are dependent on the tertiary consumers for obtaining food.
5. At scavenger level -The scavengers consume the dead and decaying organisms, hence helps in degrading them and cleaning the environment. The death of scavengers would cause an accumulation of dead matter.
6. At decomposer level - The dead matter is finally acted upon by the bacteria and fungi to produce fertile humus, necessary for the growth of the producers. Absence of the decomposers can negatively affect the growth of the producers.
