Differentiate between food chain and food web? |
|
Answer» Following are the main differences between food chain and food web. 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. |
