Which organism in this food chain will have the highest concentration of chemical pollutants?

Humans tend to eat fairly high on the marine food chain. Predatory fish - fish that eat other fish that have eaten still other fish and animals - will have some of the highest concentrations of biomagnified chemicals.

Which organism in the food chain would contain the highest concentration of chemical pollutants?

Answer. This is biomagnification, and it means that higher-level predators-fish, birds, and marine mammals-build up greater and more dangerous amounts of toxic materials than animals lower on the food chain.

Where is the most concentrated pollution in a food chain?

The concentration of a pollutant in a food chain always starts with the lowest concentration in the first level, whether plant or animal. Each successive food chain level concentrates the pollutant more in the level species.

Which level in the food chain will have the highest concentration of a toxic substance?

At each trophic level of the food chain, the toxins remain in the tissues of the animals - so the concentration of toxin becomes most concentrated in the body tissues of the animals at the top of the food chain.

Which trophic level in a food web would contain the highest concentration of chemical pollutants do to biological magnification?

The higher an animal is on the food chain (e.g. tertiary consumer such as seals), the greater the concentration of DDT in their body as a result of a process called biomagnification.

Which organism in this food chain will have the highest concentration of non-biodegradable chemicals?

Hawk will have the highest concentration of non-biodegradable chemicals. The phenomenon associated is biomagnification.

In which trophic level biomagnification is highest?

So the correct answer is 'secondary consumers'.

What part of the food chain is most affected by toxins?

In many cases, animals near the top of the food chain are most affected because of a process called biomagnification. Many of the most dangerous toxins settle to the seafloor and then are taken in by organisms that live or feed on bottom sediments.

At which level is the concentration of chemicals highest in a food chain and why?

An animal higher up on the food chain tends to have a greater concentration of chemicals because of what it eats. Even though there might be very little concentration of chemicals in the tissues of an organism at the bottom level of the food chain, the concentration of chemicals builds up as you go up the food chain.

Which trophic level in the given pyramid has lowest and highest concentration of chemical pollutants?

Answer. Top Carnivore or we can say secondary consumer has the highest concentration of toxic substances in a food chain...

How does chemicals affect the food chain?

Chemicals and toxins increase with every step of the food chain, because they bio-accumulate. The consumers nearer the top of the pyramid are exposed to everything their food has already absorbed and stored in their tissue.

What describes the concentration of toxic chemicals in the food chain?

Biomagnification, also known as bioamplification or biological magnification, is any concentration of a toxin, such as pesticides, in the tissues of tolerant organisms at successively higher levels in a food chain.

How pollution affect food chain?

Pollution disrupts the food chain by moving the toxins from one level in the chain to higher levels. Such affect the other organisms by either causing excessive growth, in case the predator dies or death (if it wipes out the prey).

Which one of the following organism is likely to show the highest concentration?

The correct option is C Snake

Which one of the following organisms is likely to show the highest concentration of DDT, once it has been introduced into the ecosystem? Q. The concentration of DDT has increased alarmingly in organisms today.

Which of the following is an example of pollutants whose concentration increases in each trophic level?

An example is DDT whose concentration increases at each trophic level.

Which trophic level has maximum number of organisms why B in which trophic level chemicals like DDT are accumulated in highest concentration?

(i) The trophic level T1 has maximum number of organisms. (ii) At trophic level 4 chemicals like DDT are accumulated in its highest concentration.

What is the top of the food chain?

At the top of the system are the apex predators: animals who have no predators other than humans.

Which level of the food chain is most affected by biomagnification quizlet?

Animals are most affected by biomagnification higher up the food chain after much accumulation.

Which organisms contain the most DDT?

Worms, grasses, algae, and fish accumulate DDT. Apex predators, such as eagles, had high amounts of DDT in their bodies, accumulated from the fish and small mammals they prey on.

What types of organisms can be affected by toxins?

The severity and type of diseases caused by toxins can range from minor effects to deadly effects. The organisms which are capable of producing toxins include bacteria, fungi, algae, and plants. Some of the major types of toxins include, but are not limited to, environmental, marine, and microbial toxins.

Why do toxic chemicals accumulate at higher trophic levels?

These lower organisms when consumed pass the toxic substances up the trophic level. The increase in toxicity is attributed to persistence and food chain energetics, which leads to substances concentration increasing progressively up the trophic levels.

Why toxins become more and more concentrated in the living tissues of organisms as they go up in the food chain?

When herbivores eat contaminated plants, the toxins accumulate in their fatty tissues. If a carnivore eats several toxin-laden herbivores, the toxins become even more concentrated in its body. This process of biomagnification continues up the food chain.

What is biomagnification example?

Biomagnification is defined as the accumulation of a particular substance in the body of the organisms at different trophic levels of a food chain. One example of biomagnification is the accumulation of insecticide DDT which gets accumulated in zooplanktons. Small fishes consume these zooplanktons.

Which of the following exhibits biomagnification a so2 B mercury C DDT D Both B & C?

Solution : Biomagnification refers to increase in concentration of the toxicant at successive trophic level. This phenomenon is well known for DDT and Hg.

Which of these will have highest concentration of non-biodegradable chemical name the phenomena?

Solution : Hawk will have the highest concentration of non-biodegradable chemicals. <br> The phenomenon associated is biomagnification.
