Question

do you think think biodegradable insecticides show biomagnification

Answer 1

Yes, I think biodegradable insecticides show biomagnification because of the following:

• An accumulation of the  toxin, including pesticides, as in tissues of sensitive species at progressively higher levels of the food chain is described as biomagnification, also called bioamplification or biological magnification.
• This rise can also be determined by a multitude of factors, including:

-When a substance can't be broken down by natural processes, it's called persistence.

-Food chain energetics is a concept in which the concentration of a material increases as it progresses up the chain of food

-Internal decomposition or drainage of the drug is slow or non-existent, owing to water insolubility.

• Biological magnification seems to be the method through which predefined substances, including pesticides or toxic substances, make their way in to other rivers, lakes and also the ocean, in which they are integrated through diet of aquatic life like zooplankton, which are then consumed by fish, which are then consumed by larger species, large animals, birds or humans. As the compounds progress up in the chain of food, they become more accumulated in tissues as well as internal organs.
• Two types of biomagnifying chemicals are there. Both are lipophilic and resistant to degradation. Novel organic chemicals are difficult to decompose because organisms have not been exposed to them before and hence have not evolved appropriate detoxification and disposal systems as just a consequence of the lack of selective pressures. As a reason, these substances are considered to be  "persistent organic pollutants," as POPs.

Answer 2

Answer:

HOPE IT IS HELPFUL 2 U

Explanation:

Biomagnification occurs when slightly larger organisms called zooplankton feed upon the contaminated phytoplankton and in turn absorb POPs into their own tissues at a higher concentration. The more contaminated phytoplankton a zooplankton eats, the more pollutants it will have in its body. In other words, the POPs can be passed from producer to consumer (to consumer, to consumer, and so on…) Biomagnification can continue all the way up the food web or chain. Because the amounts of POPs become more and more concentrated at each trophic level, some of the ocean’s apex predators are at risk of gaining potentially fatal levels of POPs within their bodies.

One large apex predator that is heavily impacted by the bioaccumulation and biomagnification of POPs is the orca. Researchers have found extremely high levels of PCBs within the blubber of Arctic orcas, making them “the most toxic animal in the Arctic.” Additionally, scientists in Japan have found that mother orcas are passing these contaminants to their young through their milk, which has high fat content. PCBs are known to cause problems with reproduction, and studies are currently being conducted to see if and how POPs are impacting orcas in other ways.

Governments are slowly starting to realize the importance of countering the negative impacts of these pollutants. The production of DDT was banned in the United States in 1972, and more chemicals are being banned each year. In 2004, the Stockholm Convention on Persistent Organic Pollutants came into effect and internationally bans the production of PCBs and other harmful chemicals. These bans have proven to be mostly effective, and the environmental levels of many of these toxins have already started to noticeably decrease.
