Question

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)?

Answer 1

Answer: birds lay eggs with soft shells

Explanation: DDT effects development of the shell and the baby bird.

Answer 2

DDT can sustain in environment there by leading to bio magnification

Step-by-step explanation:

Bio magnification is a process in which the concentration of toxic element or chemical increases in the higher order of food chain. DDT being a persistent compound in nature risk the occurrence of bio magnification in an ecosystem at higher levels.

DDT is insoluble in water and hence it is stored in fatty tissue of animals. This comes from the agricultural waste, industrial waste poured into any water body without treatment.
