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
The DDT problem is a good example of how pesticides can contaminate human health through what?
the food chain
Which member of food chain would have the highest level of DDT in animals body?
Top carnivores.
In top of the food chain why does the narrator first spray with DDT?
To help control the insects in Borneo
What event happens first in top of the food chain?
DDT is sprayed ova the country cuhh
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.
What organisms have the most pesticides?
The organisms at thetop of the food chain will contain the most DDT. These are the top carnivores (or humans if we are in the food chain).DDT builds up in food chains for several reasons:1) It is a persistent pesticide IE: it is difficult for any organisms to break it down, it is non-biodegradable.2) It is soluble in fat, so it enters the fat storage tissue (adipose tissue) and stays there.3) Organisms higher in the food chain consume DDT every time they feed on organisms lower down in the food chain, if they are contaminated with DDT.4) The biomass at each level in a food chain gets less, so the concentration of DDT will increase.The increase in concentration of pesticides in a food chain is called bio-magnification.Additional Information: Seals, Predatory Fish, Bears, Predatory Birds, Bats.
How does the narrator in the top of the food chain first try to control the insect population of Borneo?
He sprays DDT.
How does the narrator in Top of the Food Chain first try to control the insect population of Borneo?
He sprays DDT.
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
Why such a high dosage of ddt found in grebes?
Because as DDT made its way up through the food chain from plankton to grebes the concentration of insecticide magnified until it was fatally high in the birds
