The top of the food chain.
As organisms consume other organisms, the toxins are all passed up in the food chain. Therefore, the top of the food chain will have the highest concentration of toxins.
Producers have the most energy at the pyramid level because they manufacture food from inorganic raw materials.
In an energy pyramid, the most energy is found at the producer level, which consists of autotrophic organisms like plants that convert sunlight into usable energy through photosynthesis. As you move up the pyramid to primary consumers, secondary consumers, and so on, energy is lost at each trophic level through metabolic processes, heat loss, and waste production.
An ecological pyramid, specifically an energy pyramid, can be used to show the amount of energy available at each trophic level in an ecosystem. This type of pyramid illustrates the decrease in available energy as you move up the food chain, with the most energy found at the base (producers) and decreasing amounts at higher trophic levels.
An energy pyramid is like a food chain, because at the top of the pyramid, there is the most energy, and at the bottom there is the least energy. The same goes for a food chain, because the producer has 100% of the energy. The final consumer, or tursury consumer, has either little or no energy left from the primary, and secondary consumers, because they have used up almost all the energy breathing, moving and during digestion.
Cooking kills bacteria but not the toxins the bacteria made while growing. Refrigeration does prevent most bacteria but not listeria which can grow in a refrigerator. Botulism is a toxin that does not go away with boiling or cooking.
The producers are found at the bottom. They contain the most amount of energy and the energy is transferred to other organisms in the food pyramid. [Consumers].
Unfortunately biscuits are not found at the top of the food pyramid. The food pyramid has become a plate with the correct portions we are supposed to eat at meal times. Grains are an important part of our diet but not the most important.
The bottom of the food pyramid (plants mostly) have the greatest amount of energy available. The best argument for vegetarianism I ever heard.
In Peru.
The most energy in an energy pyramid is typically found at the base, with the primary producers (such as plants) converting sunlight into energy through photosynthesis. Each level up the pyramid contains less energy as it is transferred through the food chain.
Most proteins are at the top of the food pyramid because animals are protein. You can also get protein from eggs.
Producers have the most energy at the pyramid level because they manufacture food from inorganic raw materials.
http://www.disabled-world.com/artman/publish/food_pyramid.shtml has a really good picture of the food pyramid. Also, the food pyramid is updated every 5 or so years
The best way to prevent ingesting harmful toxins is to wear a face mask of some sort when working around the toxins. If you have a fear of ingesting toxins from common food sources you can always read the ingredient label that comes with most food.
junk food most likely
I would say the grain part of the food pyramid because most oils come from grain.
You can find a picture of a food pyramid at most of your health food sites. There is an old and new diagram out now. To find where Egyptian foods are in the pyramid check out a health food site.
