The document discusses the concept of biomagnification, particularly focusing on DDT (dichlorodiphenyltrichloroethane), a persistent man-made pesticide. It outlines DDT's historical use, its environmental impact as highlighted by Rachel Carson in 'Silent Spring', and the resulting public outcry that led to its ban. The document includes activities related to calculating DDT consumption through marine food webs and analyzing DDT levels in seabird eggs over time, emphasizing the ongoing concerns regarding DDT's presence in ecosystems despite its ban.

What happens to the concentration of DDT from producers to consumers?

Complete answer: It is observed that the level of DDT increases as the food chain progresses. It means, the primary consumers will have more DDT concentration than the producers, the secondary consumers will have more than primary consumers, and so on. The highest concentrations will be seen in the top carnivore.

What happens to the concentration of DDT?

The concentration of DDT increases, as it moves or travels along the food chains. Its concentration is maximum in top trophic level.

What happens to the DDT concentration in all the organisms in the ecosystem?

As animals lower on the food chain are eaten by other animals higher up, DDT becomes concentrated in the fatty tissues of predators (7,14). This continues until the primary predator of the food chain receives the highest dose, which may lead to adverse health effects.

How does DDT affect the environment?

What effects does DDT have on wildlife? DDT is slightly to moderately toxic to birds when eaten (15). DDE decreases the reproductive rate of birds by causing eggshell thinning and embryo deaths (14). DDT is highly toxic to aquatic animals (14).

What is biomagnification activity DDT in the ecosystem?

Biomagnification happens when toxic chemicals, like DDT, whose remains in the environment are consumed indirectly by organisms through food. When an organism in the higher food chain consumes the lower organism containing such chemicals, the chemicals can get accumulated in the higher organism.

What is the correct order of biomagnification of DDT?

Hence, the correct answer is Water-0.003ppm, zooplankton- 0.04ppm, small fish-0.5ppm, large fish-2ppm, fish eating birds-25ppm

What is the effect of DDT in the food chain?

DDT affects the food chain by bioaccumulating in organisms, as well as reducing population sizes that can feed higher trophic levels. A rough example of the food chain would have fish eating insects that have been poisoned with DDT.

What happens to the concentration of DDT in each trophic level?

The higher the trophic level of an organism, the higher the concentration of DDT. DDT is excreted from the body very slowly and it is stored in fat. Thus, when an organism consumes another organism, the DDT in the prey accumulates in the predator.
