because it's a chain...and the chains added together make a food web...duhh!

^ this is wrongg

no chains are a blacksmith tool a scab can be more painful depending on the size of the chain but chains are always heavier


Define food chain and food web?

Food ChainA simple chain of feeding relationship between three or four organisms is called a food chain. Food WebA food web is a diagram, of some sort, that links at least two food chains together. Food webs describe how energy is passed throughout a section of an ecosystem (or an entire ecosystem). An example of a food web:[ Grass ] -> [ Zebra ] -v[ Leaf ] -> [ Giraffe ] - [ Lion ]The transfer of food energy from the source in plants through a series of organisms with repeated eating and being eaten is the Food Chain. The interlocking pattern of Food Chains makes up the Food Web.A food chain traces the movement of energy flow from one organism to the next. A chain usually starts with an autotroph that converts energy from the sun into chemical energy (glucose). The passing of energy occurs when a heterotroph (organisms that collect chemical energy that is created by other organisms) consumes an autotroph. A food chain doesn't accurately show all the kinds of organisms that each heterotroph can consume to get energy from, so scientists invented food webs to display the various pathways that energy movement can happen in an ecosystem.


Are Tris' fear of swarming animals and Four's fear of heights really Veronica Roth's phobias in real life?

Yes, they are. The author of Divergent, Veronica Roth, has a phobia of swarming animals, like her character Tris does. She also has a phobia of heights, like her character Four does.

What are four human activities that interfere with the ecosystems food chains and food web?

Some people kill animals e.g wolves for skin. When they kill wolves they stop the food chain and kill every animal in the food chain.


Why do food chains stop at 4 organisms?

Food chains typically stop at four organisms due to the loss of energy as it moves up the chain. Each organism consumes only a portion of the energy available in the organism below it, resulting in a decrease in energy transfer efficiency. As a result, there is usually not enough energy left to sustain additional trophic levels beyond the fourth organism.


Why is there usually no more than four or five stages in a food chain?

Food chains typically have fewer stages due to energy loss at each trophic level. As energy is transferred from one organism to another, some of it is lost as heat, leading to a decrease in available energy for each successive trophic level. This limits the number of stages in a food chain to ensure energy efficiency and sustainability.


Why do most food chains consist of no more than 3 or 4 levels?

During the progression of each stage, the organisms in the food chain exert tons of energy. Most chains are broken down to four stages for that reason.
