How does a food web differ from a food chain?

Answer 1

food web goes in turns eg when a grasshopper eats grass a rat or any animal can feed on it and a human can also feed on the animal too.

while food chain is like a chain of food e.g grass to NY INSECT THEN TO AN ANIMAL THEN THE FINAL STAGE THE CONSUMER WHICH IS KNOWN AS THE MAN.

Answer 2

The food chain is the sequence in a food web, starting from a species called producers and ending in a species called decomposers. Trophic level is the position an organism is at in the food chain.

Answer 3

Trophic levels refer to each "link" within a food chain. The first level are the producers that use sunlight (usually) to form glucose. Producers then use the glucose for growth and metabolism. The next level are the primary consumers (or herbivores), followed by the secondary, tertiary, etc., consumers (carnivores). Together, the flow of energy and nutrients from the first level up through higher levels can be called a food chain. Since most organisms pass energy and nutrients to several other organisms in a system, we often refer to food webs instead of food chains (to better represent the complex nature of the system).

Answer 4

They don't, though food chains and food webs themselves differ, but mainly only in length.
