Vulnerability of food chains

Other Names:
Fragile food webs
Vulnerability of food supply

Food chains are the networks of feeding relationships which interlink different species within a biological community. Particular links in such networks may be threatened or eliminated by the action of man-made products (such as pollutants), thus placing all the members of the biological community in danger, even though the others may not be directly affected.


Destruction of the ozone layer has potentially disastrous effects on single-cell organisms like plankton, at the base of the food chain.
