    Answer: E. the food chain will be disrupted

    Explanation:

    The chemical fertilizers are the chemicals which contain essential elements which are required by the plants but not always present in the soil used for growing the crops.

    According to the given situation, excessive use of fertilizers likely to affect the food chain of the agricultural ecosystem. As these fertilizers will be added up to the food chain. These fertilizers can be poisonous for microbes which act as decomposers of organic matter present in the soil. Also some of the insects will also get affected by the toxic chemicals. The plants will absorb these toxic chemicals which will be transmitted to the insects, herbivorous animals and to the humans. Hence, the toxicity will affect the population size of the susceptible species.

    Therefore, the entire food chain will be disrupted by this way.
