i don't understand your question.

are you talking about the effects of bioaccumulation?

1 answer



Yes, bioaccumulation is a noun. It refers to the gradual accumulation of substances, such as pesticides or heavy metals, in living organisms over time, resulting in higher concentrations in the organisms than in the surrounding environment.

The physical property of DDT that contributes to its bioaccumulation in animals is its inability to break down easily. This results in it being stored in the fatty issues of animals.

Pollution refers to the presence of harmful contaminants in the environment, while bioaccumulation is the gradual accumulation of pollutants in living organisms. Both can have negative impacts on ecosystems and human health. The key difference is that pollution is the introduction of contaminants into the environment, while bioaccumulation is the uptake and accumulation of these contaminants by organisms in the food chain.

Bioaccumulation is the gradual build up of synthetic and organic chemicals in living organisms over time. These chemicals can come from sources like food, water, and air, and tend to accumulate in higher concentrations as they move up the food chain. Bioaccumulation can have harmful effects on organisms and ecosystems.

The concept of bioaccumulation is when there is an unusual accumulation of a substance such as pesticides or toxins in a living organism. This could refer to something such as mercury being found in fish. This type of contamination can occur from water, food, air or soil.

1 answer


Bioaccumulation is the accumulation of a substance in an organism's body over time, typically from its environment. Biomagnification, on the other hand, is the increase in concentration of a substance as it moves up the food chain, with higher trophic levels accumulating higher levels of the substance. In essence, bioaccumulation occurs within individual organisms, while biomagnification occurs across different trophic levels.

In a direct pathway for bioaccumulation, organisms take in contaminants directly from the environment through processes like ingestion or absorption. In an indirect pathway, organisms accumulate contaminants by consuming other organisms that have already bioaccumulated the contaminants.

2 answers


Bioaccumulation. This occurs when pollutants are consumed by organisms at lower trophic levels and then get stored in their tissues. As these organisms are consumed by predators, the pollutants accumulate in higher concentrations in their tissues, posing a greater risk to organisms at the top of the food chain.

Yes, an animal could die from bioaccumulation if toxic substances build up in its body to a level that interferes with normal physiological functions. This can happen if the animal consumes contaminated food or water over a period of time, leading to high concentrations of toxins in its tissues that can be lethal.

Pesticides that are easily broken down in the environment, have low persistence, volatility, and tendency to accumulate in living organisms are less likely to contribute to bioaccumulation. Examples include microbial pesticides, botanical pesticides, and certain biopesticides that have specific target organisms and low environmental persistence.

Bioaccumulation occurs when a plant absorbs an insecticide substance at a rate greater than that at which the substance is lost.

1 answer


Bioaccumulation is the process by which chemicals or substances accumulate in living organisms over time, often at concentrations higher than those found in the surrounding environment. This can occur through ingestion of contaminated food or water, or through absorption from the environment. Bioaccumulation can result in negative health effects for organisms higher up in the food chain.

Top predators in the food chain, such as apex predators like sharks or eagles, are more likely to have the highest concentration of pollutants due to bioaccumulation. As pollutants move up the food chain, they become more concentrated in the tissues of organisms at higher trophic levels.

When chemicals move from one organism to another through links, it is called bioaccumulation or biomagnification. Bioaccumulation refers to the accumulation of a chemical in the tissues of an organism over time, while biomagnification refers to the increase in concentration of a chemical as it moves up the food chain. Both processes can have negative impacts on the health and well-being of organisms.

Bioaccumulation refers to the accumulation of a substance in an organism's tissues over time. In the case of DDT, a pesticide used in the past, it bioaccumulates in the fatty tissues of organisms as it moves up the food chain. This can lead to higher concentrations of DDT in organisms higher up the food chain, posing potential risks to those predators.

Pelican meat is not commonly consumed by humans due to its strong flavor and potential health risks. It is not recommended for consumption due to concerns about bioaccumulation of toxins in pelicans.

1 answer


Bioaccumulation is a process by which chemical substances are ingested and retained by organisms, either from the environment directly or through consumption of food containing the chemicals. Biomagnification is a cumulative increase in the concentration of a persistent substance in successively higher levels of the food chain. Bioconcentration refers to the cumulative effects of bioaccumulation and biomagnification.

Carnivores are generally not consumed due to concerns about bioaccumulation of toxins and diseases from the animals they may have consumed. Additionally, carnivores tend to have tougher and leaner meat compared to herbivores, making them less desirable for consumption.

DDT originally enters the food chain through runoff from agricultural fields or from direct application to crops. It can then be absorbed by plants and accumulate in the tissues of animals that eat these plants. This process is known as bioaccumulation.

Bioaccumulation is the building up of toxins in a food chain. Since toxins like, for instance, DDT, are not soluble in water and are instead stored in the fatty tissues, their levels raise each tier you go up on the food chain. I'll give you an example...

Plankton, at the bottom of the food chain, eat small particulates and algae, but also take in small levels of mercury.

Small fish then eat the plankton. The mercury concentrates further - remember, DDT and mercury are not water soluble toxins, so they can't be passed through urine or feces.

Large fish may eay up to 1,000 small fish in their lifetime. The mercury reaches dangerous levels for humans, and may cause genetic mutations in the fish's reproductive habits (ie, size of eggs, number of eggs, etc).

Oceanic birds eat large and small fish. The mercury causes more genetic defects, including thinner eggshells.

As you can see, bioaccumulation poses a real danger to certain ecosystems, especially since many areas were sprayed with DDT in the 60's and 70's.

DDT is a fat-soluble compound, meaning it dissolves in fats and oils but is not water-soluble. This property allows DDT to accumulate in the fatty tissues of organisms, leading to potential bioaccumulation and biomagnification in the food chain.

Predators at the top of the food chain are at risk from bioaccumulation because they consume many prey animals containing toxins, which then accumulate in their bodies as these toxins move up the food chain. Since predators have fewer organisms feeding on them, the toxins they've accumulated have limited opportunities to be passed along and harmlessly expelled, leading to a higher risk of toxicity.

Pollution can impact whales in two ways:

  • As top predators (they eat things that eat things,that eat things) they are at the receiving end (get aconcentrated dose of) of the bioaccumulation of contaminants like PCBs and mercury.
  • Low levels of pollution and climate change can remove the species of food that whales eat. They then starve.

Any fish that is higher up in the food chain has the effects of bioaccumulation. This is why you can't eat too much tuna due to mercury poisoning and things like that. So, I guess little fish with plants would be safer.

Total Petroleum Hydrocarbons (TPH) can impact human health and the environment due to their toxicity and potential for bioaccumulation. Exposure to TPH can cause respiratory issues, skin irritation, and other health problems. In the environment, TPH can contaminate soil and water, leading to adverse effects on plant and animal life.

1 answer


The concentration of toxins tends to increase as you move up the food chain, a phenomenon known as bioaccumulation. This occurs because organisms at higher trophic levels consume many individuals from lower trophic levels, leading to the accumulation of toxins in their bodies. This can have harmful effects on top predators.

Iodine is absorbed by Nitella sp., a sea-dwelling alga, through a process called bioaccumulation. The alga absorbs iodine from the surrounding water through its cell walls and accumulates it in its tissues. This accumulation process allows the alga to maintain adequate levels of iodine for its metabolic functions.
