How does the narrator in the top of the food chain first try to control the insect population of Borneo?
He sprays DDT.
Which organism had the most DDT in their bodies?
Birds of prey, such as peregrine falcons and bald eagles, had some of the highest levels of DDT in their bodies due to biomagnification through the food chain. This accumulation of DDT caused reproductive issues and population declines in these species. Efforts to ban DDT and other harmful pesticides have helped to reduce these impacts.
How many times greater ias the concentration of DDT in fish than seawater?
The concentration of DDT in fish is typically thousands of times greater than in seawater due to biomagnification, where DDT accumulates in organisms higher up the food chain. This accumulation occurs as fish consume smaller organisms with DDT residues, leading to higher concentrations in their tissues.
Ddt and related compounds are primarily stored in?
DDT or dichlorodiphenyltrichloroethane is a colorless crystalline substance that is used as an insecticide. DDT and some related compounds are primarily stored in fats and other organic solvents.
What are the disadvantages of using DDT?
DDT is harmful to the environment and can persist in the soil and water for a long time. It can also bioaccumulate in the food chain, leading to negative health effects in organisms at higher trophic levels, including humans. Overuse of DDT has also contributed to the development of DDT-resistant insects.
How did DDT enter the food chain?
DDT entered the food chain because it was in the water of the fish that bald eagles ate.
What is the relationship between biological magnification and the reduction of the bald eagle population by pesticide DDT?
because DDT accumulates in fatty tissue, DDT concentrations increase as this chemical moves up in the food chain because at the top of the food chain, DDT concentration has increased almost 10 million times
What happened first in top of the food chain?
DDT is sprayed ova the country cuhh
How does the narrator in the top of the food chain first try to control the insect population of Borneo?
He sprays DDT.
Why does osprey contain large amounts of DDT?
DDT concentration is higher in ospreys because they eat the animals that have concentrations of DDT in it. As DDT passes up the food chain it gets more and more concentrated. THis is due to the 10% rule. wiki it.
The DDT problem is a good example of how pesticides can contaminate human health through what?
the food chain
What event happens first in top of the food chain?
DDT is sprayed ova the country cuhh
In top of the food chain why does the narrator first spray with DDT?
To help control the insects in Borneo
Which member of food chain would have the highest level of DDT in animals body?
Top carnivores.
What causes the cats to die in top of the food chain By TC Boyle?
It was the gekoes that killed them because of the DDT
How does the narrator in Top of the Food Chain first try to control the insect population of Borneo?
He sprays DDT.
What is meaning by bioaccumulation and how does it apply to DDT?
Bioaccumulation refers to the accumulation of a substance in an organism's tissues over time. In the case of DDT, a pesticide used in the past, it bioaccumulates in the fatty tissues of organisms as it moves up the food chain. This can lead to higher concentrations of DDT in organisms higher up the food chain, posing potential risks to those predators.
