What trophic level is most affected by environmental toxins such as DDT?
The trophic level most affected by environmental toxins such as DDT is usually the top predators, such as apex predators or carnivorous animals. This is because toxins bioaccumulate as they move up the food chain, reaching higher concentrations in organisms at higher trophic levels.
Does ddt accumulate in the environment?
DDT is fat-soluble and tends to build up in the fatty tissues of predators and scavengers.
Did DDT affect song birds?
no!
Why did ddt only affect to carnivores?
Not true. Birds have been affected by DDT and so have fish.
How did DDT not affect Eagles?
It did not improve their 'hatch-rate'.
As ddt moves up the trophic levels in food chains its concentration?
increases. This is known as biomagnification, where organisms higher up in the food chain accumulate higher levels of DDT due to consuming prey that have ingested or absorbed the chemical. This can lead to harmful effects on top predators due to the higher concentrations of DDT in their bodies.
How styxosaurus affect in food chain?
The plesiosaurs were the top predators of the food chain at that time
Why ddt is mostly found in tertiary or top consumers?
DDT (dichloro-diphenyl-trichloroethane) is a persistent organic pollutant that accumulates in the environment and is particularly prone to biomagnification. As it moves up the food chain, it becomes more concentrated in the tissues of organisms, especially in top consumers or tertiary consumers, which feed on multiple lower trophic levels. This accumulation occurs because these higher-level predators consume large quantities of prey that may have already accumulated DDT, leading to significant concentrations in their bodies. Consequently, top consumers often exhibit higher levels of DDT, posing risks to their health and the ecosystems in which they reside.
How do you do your finisher in wrestling encore?
go to the top rope. and then DDT
Why such a high dosage of ddt found in grebes?
High levels of DDT found in grebes can be due to bioaccumulation, where the pesticide builds up in the food chain reaching toxic levels in top predators like grebes. Grebes consume contaminated fish and aquatic insects which leads to a high concentration of DDT in their bodies. Efforts to decrease the use of DDT and monitor its presence in the environment are important to protect wildlife like grebes.
Are other predators get affected by DDT?
Yes, other predators are affected by DDT, particularly those higher up in the food chain. DDT can accumulate in the bodies of organisms through a process called biomagnification, leading to toxic effects such as reproductive failures, thinning of eggshells, and neurological issues. Birds of prey, such as eagles and osprey, were notably impacted by DDT, leading to significant population declines. The chemical's persistence in the environment further exacerbates these effects, posing risks to various wildlife species.
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.
