The energy which plants capture from the sun during photosynthesis may end up in the tissues of a hawk via a bird the hawk has eaten, the insects eaten by the bird, and the plant on which the insects fed. The plant-insect-bird-hawk system is called a food chain, and each stage a trophic level.

FOOD DEFENCE AND FOOD SUPPLY CHAIN
2021In EU countries and beyond, HACCP are legal requirements throughout the whole food supply chain. The fact is that HACCP effectively control only accidental contamination and do not recognize intentional contamination, which is now increasingly significant due to the increasing incidence of intentional contamination throughout the food supply chain.

Several examples of food chain changes in PCB residue composition have been introduced in Chapter 5. Factors favoring accumulation of specific congeners have been interspersed throughout the text. These factors include air transport and herbage uptake (Chapter 4) and air H water H sediment exchanges as they influence the accumulation by aquatic and ...
