Which of the Following Is the Best Description of Bioaccumulation

It usually occurs when an organism ingests a particular substance at a faster rate than it can metabolize or excrete. An increase in the concentration of a chemical in a biological organism over time compared to the chemicals concentration in the environment.

Bioaccumulation Environmental Science Science Projects Ecology

Bioaccumulation is a process of the accumulate of the chemical constituent that doesnt decompose or that dont leave the digestive tracts of the animal and these keep on spreading with the passage of time.

. An increase in the concentration of a substance inside an organism. Many chemicals including dioxins polycyclic aromatic hydrocarbons PAHs polychlorinated biphenyls PCBs and organ metallic forms of metals bio-accumulate in animal fat Hill 1997 and are difficult to degrade. It happens over time.

Biosorption and bioaccumulation involve interactions and concentration of toxic metals or organic pollutants eg. Describes the entrance of a chemical into an organism. Thus bioconcentration and bioaccumulation occur within an organism and biomagnification occurs across trophic food chain levels.

It explores causality at great length cause-and-effect associations. The term bioaccumulation is used to refer to storage of a pollutant at levels higher than found in the environment. Taking in chemicals faster than a living organism can break it down and use.

Accumulation in living things can occur whenever metals are taken up and stored faster than they are metabolized or excreted Markich et al 2001. 2 Plantsanimals from which of. An increased concentration of a toxic chemical the higher an animal is on the food chain.

True False QUESTION 2 This is an intricate field that delves into the environmental causes of diseases. When an animal consumes food having DDT residue the DDT accumulates in the tissue of the animal by a process called bioaccumulation. The accumulation over time of a substance and especially a contaminant such as a pesticide or heavy metal in a living organism.

The increase in chemical concentration in animal tissues as the chemical moves up the food chain-biomagnification is one organism bioaccumulation is an entire food chain. They enter into the living systems via water or food. Dyes in the biomass either living bioaccumulation or non-living biosorption.

An increase in the level as one moves higher in the food chain. The two causes of bioaccumulation are the amount of the chemical coming into the living organism faster than the organism. An increased concentration of a chemical within an organism over time-biomagnification.

Bioaccumulation is when a chemical toxin is taken into an organism and builds up in the organisms tissues. What is Bioaccumulation. Bioaccumulation occurs via food chains.

Bioaccumulation factor BAF The ratio of a substances concentration in tissue of an aquatic organism to its concentration in the ambient water in situations where both the organism and its food are exposed and the ratio does not change substantially over time. Bioaccumulation in pets and other organisms would be examined too on a biological level to show the far-ranging impacts of lead and why students should be concerned about its occurrence anywhere in the biosphere. The higher an animal is on the food chain eg.

Bioaccumulate is in the form of toxins and other untreated stuff released into the water ecosystems. Bioaccumulation occurs within a trophic level and is the increase in concentration of a substance in certain tissues of organisms bodies due to absorption from food and the environment. Understanding the dynamic processes of bioaccumulation can have important ramifications in protecting.

Tertiary consumer such as seals the greater the concentration of DDT in their body as a result of a process called biomagnification. Bioaccumulation refers to the increase in concentration of a pollutant in an organism. QUESTION 1 Bioaccumulation is when toxic substances such as heavy metals become more concentrated and potentially more harmful as they move up the food chain.

Lead and fluoride bio. Bioaccumulation involves relative to the ambient value an increased concentration of a metal in a biological organism over time. Accumulation of a toxic chemical in the tissue of a particular organism.

Finally this work suggests that the likelihood for PAHs to have large. The processes play an important role. Bioaccumulation is the build-up of chemicals inside of living organisms.

Bioaccumulation refers to the build-up of a toxic chemical in the body of a living organism. These substances could be heavy metals pesticides or organic chemicals. Information exists on the bioaccumulation phenomenon there is a critical need for improved methods of assessing the presence of bioaccumulative chemicals.

Biology questions and answers. Biomagnification refers to the increased concentration of a toxic chemical the higher an animal is on the food chain. Which of the following is one of the main causes of bioaccumulation.

Bioaccumulation is the accumulation of toxic substances in living organisms. Of the bioaccumulation assessment methods examined for PAHs the use of SPMDs offers the most potential. Bioaccumulation refers to the accumulation of a toxic chemical in the tissue of a particular organism.

What essentially happens is that an organism absorbs the chemicals across their skin or otherwise takes.
