I want to know the answer to the following question:
What is one type of pesticide?
All the background I'm provided with is that "Pesticides can also be considered as either biodegradable pesticides, which will be broken down by microbes and other living beings into harmless compounds, or persistent pesticides, which may take months or years before they are broken down: it was the persistence of DDT, for example, which led to its accumulation in the food chain and its killing of birds of prey at the top of the food chain.". Is that enough to answer the question?
