Define biological magnification and explain why humans are often more severely affected?
Biological magnification: the process by which pollutants become more concentrated in successive trophic levels of a food web (accumulation of pollutants in fatty tissues of a predator) Humans are often more severely affected than earlier trophic levels due to biological magnification. The ppm (parts per million) is the unit of measurement for concentration of chemicals like pollutants and augment to a degenerative degree in higher trophic levels. Humans are consumers and higher in the food web, thus subject to the malicious effects of biological magnification of toxins.
When biological magnification occurs in a community one expects chemical concentration in the tissues of lower trophic levels such as grasses to be what the chemical concentration?
Lower trophic levels such as grasses are generally expected to have lower chemical concentrations compared to higher trophic levels due to biomagnification. As chemicals move up the food chain, they become more concentrated in tissues. This is because organisms at higher trophic levels consume many individuals from lower trophic levels, leading to an accumulation of chemicals in their bodies.
What is the name of this process that causes the loss in energy of trophic or feeding levels?
This process is known as energy loss or energy transfer inefficiency in trophic levels. As energy moves up the food chain, it is lost through heat, metabolic processes, and other inefficiencies. This results in only a small portion of energy being passed from one trophic level to the next.
In the photosynthesis process what trophic level occur?
Photosynthesis occurs at the producer trophic level. Producers, such as plants, algae, and some bacteria, are able to convert sunlight into energy through photosynthesis, which forms the base of the food chain for other organisms.
What is it called when 10 percent of the energy in a organism is passed on to another organism?
This transfer of energy from one organism to another, with approximately 10% efficiency, is known as a trophic transfer or trophic transfer efficiency. This process occurs as energy moves through different trophic levels in a food chain or food web.

This is because organisms at higher trophic levels consume many individuals from lower trophic levels, leading to an accumulation of chemicals in their bodies.
What are the causes of biological magnification?
Biological magnification is caused by the accumulation of toxic substances in organisms higher up the food chain. This process occurs because these substances are not easily metabolized or excreted, leading to increasing concentrations as they move up through trophic levels. Primary sources of these toxins include pesticides, heavy metals, and certain organic pollutants.
What organism is effected most by biological magnification?
tertiary consumer
What is the process concentrations of harmful substances increase in organisms at higher tropic levels in a food chain known as?
This process is called biomagnification. It occurs when toxic substances accumulate in the tissues of organisms as they consume prey with increasingly higher concentrations of harmful substances. As these toxins are passed up the food chain, the concentrations become more concentrated in organisms at higher trophic levels.
How does bio magnification compare with the energy pyramid?
Bio magnification is the process where toxins become more concentrated as they move up the food chain, whereas the energy pyramid shows the flow of energy through trophic levels with energy decreasing as it moves up. Both concepts illustrate the transfer of substances (toxins or energy) through an ecosystem, but in different ways.
How does pesticide residue become more built up as the food chain increases in terms of biomass?
Pesticides increase in higher trophic levels due to Bilogical magnification .
What is the term for each step in the transfer of energy and matter within a biological community?
The term for each step in the transfer of energy and matter within a biological community is a trophic level. Trophic levels represent the different levels in a food chain or food web where organisms obtain their energy.
What percentage of energy is lost in each trophic transfer?
The ten percent law suggests or implies that exactly 90% of the energy is lost in the transfer at each trophic level, and that only 10% is passed on as useable biological energy.
What is the name of this process that causes the loss in energy of trophic or feeding levels?
This process is known as energy loss or energy transfer inefficiency in trophic levels. As energy moves up the food chain, it is lost through heat, metabolic processes, and other inefficiencies. This results in only a small portion of energy being passed from one trophic level to the next.
What is a diagram that shows an ecosystem's lost of energy at each level of the food chain?
A diagram that shows an ecosystem's loss of energy at each level of the food chain is called an energy pyramid. It depicts the decrease in available energy as it moves up trophic levels due to the inefficiency of energy transfer between organisms. Typically, only about 10% of energy is passed on to the next trophic level, with the rest being lost as heat through metabolic processes.
What would be some of the properties of molecules that could be candidates for biological magnification?
Such as Mercury accumulation in humans who eat large amounts of fish. During the 1950's, many people who consumed seafood from Minamata Bay in Japan, has neurological damage and abnormal celle effects. Also, DDT is a prime example. It affected Gerbes (a water bird), who ingested fish contianing the toxins after they ate midges.
