Question

tabulate the difference between the food chain and the food web according to the 5 marks

Answer 1

Food chain is a single linear pathway through which food energy and nutrients travels in the ecosystem while food web is number of interconnected food chains through which energy and nutrients travels in the ecosystem.In food chains, usually member of high trophic level feed upon a single type of organism of lower trophic level while in food web members of higher trophic level feed upon many organisms of lower trophic level.In food chains, separate and isolated food chains increases the instability of the ecosystem. In food web, stability of the ecosystem increases by the presence of complex food webs.Food chains have no effect on improving the adaptability and competitiveness of the organisms while more complex food webs improves the adaptability and competitiveness of the organisms.

Answer 2

food chains are the sequence of living organisms in a community in which 1 organisms consumes another organism to transfer food energy whereas food webs are inter connected food chains operating in the ecosystem which establish a network of relationships between various species.
