How does the narrator in the top of the food chain first try to control the insect population of Borneo?
He sprays DDT.
Why is DDT so harmful to an ecosystem?
DDT is a pesticide that was used to kill bugs. It's bad for the environment because it was killing the animals that would eat those bugs once they were dead, and the population of those animals was decreasing fast. It was banned once scientists realized what it was doing to the animals.
How many times greater ias the concentration of DDT in fish than seawater?
The concentration of DDT in the fish is 430,000 times greater than the concentration of DDT in the water.
What scientific studies support the decision to ban DDT?
Eagle populations recovered after the ban on DDT.
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.
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

In top of the food chain why does the narrator first spray with DDT?
To help control the insects in Borneo
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.
