e., para-para). To draw the most common isomer of DDT, we need to understand its structure. DDT is a synthetic pesticide that consists of three chlorine atoms attached to a central carbon atom. The most common isomer of DDT is the para-para isomer, where the Show more…

1. DDT is also toxic to fish and aquatic invertebrates. Based on what you know about ecosystems and food chain dynamics, what are some potential impacts to an aquatic ecosystem that receives a particularly high dose of DDT (i.e., a much higher original concentration of DDT in the water)?

DDT is an insecticide that can remain in the bodies of insects and then is transferred to the fat of the animals who eat the insects. Based on what you know about bioaccumulation, who would be most impacted by DDT? birds who eat the insects (trophic level 2) small mammals who eat the insects (trophic level 2) birds of prey who eat small mammals and other birds (trophic level 3) all are equally affected

Dichlorodiphenyltrichloroethane(DDT) is a potent insecticide rarely used today because of its effects on other forms of life. In insects, DDT disrupts sodium channel function, leading to eventual death. Mosquitos have developed resistance to DDT and other insecticides that function in a similar fashion. Suggest two means by which DDT resistance might develop.
