Примери за food chain

• The persistent chlorinated hydrocarbons—DDT and its relatives—last for a long time after being released into the environment, concentrating at various points in the natural food chain and often in man himself. 

• Among the indirect ways, irrigation of the crops with the possible passage of the agents into the food chain can be included.

• In fact, through irrigation, the microorganisms present in the water can contaminate crops, then pass into the food chain and eventually infect humans.

• As if we possessed a carnivore's teeth and digestive tract, thoughtless cliché places us 'at the top of the food chain'.

• Virtual creatures interact with each other based on a series of needs and drives, as well as a loosely predetermined hierarchy and food chain.

• As a result of this they contaminate poultry carcases and enter the human food chain.

• This implies a risk for transfer of this emerging pathogen in the food chain.

• The mammal results reflect a variety of accumulation processes depending on the geographic location, habitat, and position in the food chain.

• The more hydrophobic organochlorines partition quickly onto soil and plant surfaces, from which they are assimilated in the food chain through diet.

• The food chain in these bromeliads should be based mainly on detritus.

• Ecotoxicological study of platinum using an experimental food chain.

• The toxins and their metabolites are concentrated in the food chain when carnivorous fish prey on smaller herbivorous fish.

• This suggests that middling caciques' territorialization can be related to changes occurring higher up the political food chain.

• Pursuing parasites up the food chain : implications of food web structure and function on parasite communities in aquatic systems.

• Thus, there is a greater potential for low concentrations of fat-soluble environmental contaminants to accumulate and have effects at the top of the food chain.

• This upwelling brings nutrients that support the base of the food chain.
