What are agro-chemicals and mention their effects?

(N/A) Agro-chemicals are chemical substances used in agriculture to enhance crop production,primarily including inorganic fertilizers,pesticides,herbicides,and insecticides.
The effects of agro-chemicals are as follows:
$1$. Toxicity: Pesticides and insecticides are toxic to non-target organisms,which are essential components of the soil ecosystem.
$2$. Biomagnification: These chemicals can accumulate in the food chain,leading to biomagnification in the terrestrial ecosystem.
$3$. Eutrophication: Run-off from agricultural fields containing fertilizers leads to nutrient enrichment in water bodies,causing eutrophication in aquatic ecosystems.
