Absorption and accumulation of toxic chemicals up the food chain is a definition of what word?
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.

When chemicals move from organism to another through links it is called?
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.
The process by which non-biodegradable pollutants become more concentrated near the top of a food chain is called?
The tendency of chemicals to become more concentrated as they move up the food chain is known
What is meaning by bioaccumulation and how does it apply to DDT?
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.
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.
In the food chain how much of the Sun's energy is lost as heat before it reaches a producer?
About 90% of the Sun's energy is lost as heat before it reaches a producer in the food chain. This loss occurs through processes such as reflection, absorption, and transmission in the Earth's atmosphere.
What is the name of the process in which a harmful chemical enters the food chain and gets concentrated in the food chain?
Bio-accumulation.
Structure assisting absorption of long-chain fats?
Micelle
What is the definition for classification key?
It is a a chain
Why does a protein need an amino acid chain?
A protein is by definition, a chain of amino acids.
What is the science definition for a food wed?
food chain
What is the definition of competition with regard to the food chain?
yes
What is accumulation of pollutants at successive levels of the food chain.?
The accumulation of pollutants at successive levels of the food chain is known as biomagnification. This process occurs when toxic substances, such as heavy metals or pesticides, are taken up by organisms and become increasingly concentrated as they move up the food chain. Predators at higher trophic levels ingest multiple prey, leading to higher concentrations of these pollutants in their bodies. As a result, top predators can experience significant health risks and ecological impacts due to this accumulation.
When chemicals move from organism to another through links it is called?
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.
What food is at the top of the food chain with the highest level of toxic chemicals?
Humans.
The process by which non-biodegradable pollutants become more concentrated near the top of a food chain is called?
The tendency of chemicals to become more concentrated as they move up the food chain is known
What is the role of the bile chain in the digestive process?
The bile chain plays a crucial role in the digestive process by breaking down fats into smaller molecules that can be easily absorbed by the body. It also helps in the absorption of fat-soluble vitamins and aids in the digestion and absorption of nutrients in the small intestine.
Why are decomposes important to the food chain?
They turn dead organisms into chemicals that norishes the land.
