They accumulate as you move up the food chain because,They travel from organism to organism.For example,it may enter a food chain when it's absorbed by a plankton,and the pollutant is passed on to which ever organism eats the plankton,and it keeps on going on.

It decreases.
I think what you are referring to is a food chain, It is a series of energy steps from plants to animals and more animals in the form of food.
what happens is that the energy that was to start with will be broken and half of that will go to continue the cycle because the energy that does not move on is being used by the producer, consumer or scavenger depending on which stage of the food chain or web it is on.
The energy decreases as you move step to step in a chain The first organism (primary consumer) that eats the producer (green plants) will have the most number
humans are an aswer that an organism can move on their own
The energy decreases as you move step to step in a chain .........................................The first organism (primary consumer) that eats the producer (green plants) will have the most number of energy................................while the last organism in the chain (top predator) will have the least number of energy in the chain.
plant
Biomass accumulates Think of it as a pyramid If the animals at the bottom consume a little then the next step up will have a little more in them because they just absorbed all of it when you get to the top you will have the highest concentration in the entire food chain.
it helps food circulate and remove waster
Hello
basic terms we are discussing here. Bioaccumulation refers to how pollutants enter a food chain; biomagnification refers to the tendency of pollutants to concentrate as they move from one trophic level to the next. Here are some definitions of these terms: Bioaccumulation: increase in concentration of a pollutant from the environment to the first organism in a food chain Biomagnification: increase in concentration of a pollutant from one link in a food chain to another
