Compare Food Chains and Food Webs?

Madlyn Fallis: Never thought too much about this

Raelene Cunnick: I rather prefer food chains

Len Dalba: food chain:The simplest representation of energy in a community. At the base is energy stored in plants, which are eaten by small organisms, which in turn are eaten by progressively larger organisms; the food chain is an oversimplification in that most animals do not eat only one type of organism.------------------food web:the interconnected feeding relationships in an ecosystem. These relationships can be complex; some organisms may feed on more than one trophic level, or changes may occur depending on a species' life history stages or the availability of food.--------------------------------Difference between food chain and food web:FOOD CHAINS FOLLOW A SINGLE PATH AS ANIMALS EAT EACH OTHER. EXAMPLE:GRASS (is eaten by a) GRASSHOPPER (which is eaten by) a FROG (which is eaten by a) SNAKE (which is eaten by a) HAWK FOOD WEBS SHOW HOW MANY ANIMALS ARE INTERC! ONNECTED BY DIFFERENT PATHS. EXAMPLE:TREES produce acorns which act as food for many MICE and INSECTS. Because there are many MICE, the WEASELS, SNAKES, and RACOONS, have food. The insects in the acorns also attract BIRDS, SKUNKS, and OPOSSUMS. With the SKUNKS, OPPOSUMS, WEASELS and MICE around, HAWKS, FOXES, and OWLS can find food. They are all connected!FOOD WEBS show how plants and animals are connected in many ways to help them all survive. FOOD CHAINS follow just one path as animals find food....Show more

Bryant Chaudhry: Food ChainThe series of organisms of an ecosystem through which the food and energy present in it and passes with each member is called food chain. A food chain consists of producers (green plants), consumers (animals and man) and decomposers (micro organisms). Basically there are two types of food chains: grazing food chain and detritus food chain.Food WebIn an ecosystem single food chains! never occur. The same organisms may operate at more than one ! tropic level. So different food chains are inter connected. Thus, in an ecosystem several food chains are linked together and intersect each other to form a complex network called food web.Definition: A number of food chains form a interlinking pattern forming a web like arrangement known as food web.Food Chain vs Food Webfood web and food chain 1. It is the single straight pathway through which food energy travels in the ecosystem2. Usually members of higher trophic level* feed upon a single type of organisms of lower trophic level3. Isolated or separate food chains increases the instability of the ecosystem4. It does not have any effect on improving the adaptability and competitiveness of the organismsFood Web1. It consists of number of interconnected food chains through which food energy travels in an ecosystem2. Usually members of higher trophic level feed upon many organisms of lower trophic level3. Presence of complex food webs increases the stability of the ecosystem! 4. More complex food webs improves the adaptability and competitiveness of the organisms...Show more

Chet Nozick: food chains are simple constructed ways to represent who eats whom but food webs are complicated ways

Cliff Tyre: donno exactly.

Rosalyn Olivera: nothing really different
