, 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)?
2. Do you think DDT has the potential to cause more long-term harm to an
estuary ecosystem or a terrestrial (on land) ecosystem? Why?
