Why did ddt only affect to carnivores?
Not true. Birds have been affected by DDT and so have fish.
Has any other countries banned DDT?
Practically all countries banned DDT.
What are the pros and cons of DDT?
DDT is a very efficient insecticide but also is very toxic for other animals.
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.
Why is DDT still a controversial issue?
Because DDT is a very efficient insecticide but also is toxic for other organisms.
What trophic level is most affected by environmental toxins such as DDT?
The answer is top predators.
What raptors are affected by DDT?
ALL raptors are affected by DDT, because they prey upon what's been poisoned. Check out the related link listed below:
What was an animal which wasn't affected by DDT?
Cockroaches.
Does ddt accumulate in the environment?
DDT is fat-soluble and tends to build up in the fatty tissues of predators and scavengers.
Why did ddt only affect to carnivores?
Not true. Birds have been affected by DDT and so have fish.
What is the relationship between the trophic level of an organism and the concentration of DDT in its body?
If an animal on a high trophic level eats other organisms on a lower trophic level effected by DDT, the animals level will be affected.
What is one of the diseases that makes bald eagles die?
DDT was a pesticide that was used to kill bugs on farms. But when pretadors of those bugs were eaten by other predators the level of DDT rose and made the Bald Eagles egg shells very thin and usually the bald eagle would die. DDT is now outlawed, but the levels of DDT are still in fish and insects.
Has any other countries banned DDT?
Practically all countries banned DDT.
Why are 2nd order consumers are more likely to be affected by the DDT than the 1st order consumers?
BIOACCUMULATION
What are the pros and cons of DDT?
DDT is a very efficient insecticide but also is very toxic for other animals.
What animal was affected by the use of DDT to point of becoming an endangered species?
The Bald Eagle, and other raptors such as the Peregrine Falcon, and Osprey populations were devastated by DDT. The long term exposure nearly wiped them out. Many other birds were affected as well, Robins in one instance were killed outright on a campus when the trees were sprayed to protect them from a disease. But the raptors suffered the worst exposure, the DDT stayed in the food chain creating a domino effect, so they ingested it in greater quantities. For more details, please see the sites listed below.
