Not all of the energy taken in by one animal is passed on to the next. Some of the energy is wasted through respiratory losses (heat, movement, metabolic functions), some is excreted, some of the animals die and some is contained in inedible matter. When an organism is ingested, only a small amount of the energy is actually taken in. This continues along each trophic level until the energy available (usually after the 5th trophic level) is not enough to support this organism. This results in the food chain ending because it has 'run out of energy'.

How many food chains are there total in the world?
food chains are generally short,most food chains have anywhere from 3 or 4 links.food chains are generally short,most food chains have anywhere from 3 or 4 links.4 types
What is a complex network of food chains?
When all food chains in a habitat are joined together in some way, they form a food web. They are normally several food chains all joined up together, and may include the same predator or prey more than once in a food chain. Food webs are slightly more complex than food chains, and may sometimes be harder to read and understand. hope this helps
Why are food weds more useful than food chains?
That is because people usually understand it better.
Why do food chains rarely consist of more than a few types of organisms?
This happens because the quantity of energy available in the organisms as food to the next trophic level decreases as you move through the food chain. For example, there may be 1000 Calories of food available if you eat the grass in a section of meadow, but only about 100 Calories in the grasshoppers in that section of meadow. That may not be enough food to support the things that eat grasshoppers, and so on. This limits the length and diversity of food chains. The longest and most complex food chains are in the open ocean!
Why does a food web tell more about an ecosystem than a food chain does?
because a food chain only shows one way energy could flow, while a food web shows multiple ways. For example, a food chain might say: grass-mouse-hawk. but it could also say: grass-mouse-snake-hawk. Or even: grass-mouse-weasel-hawk. However, a food web might show all of these.
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.
Why is there usually no more than four or five stages in a food chain?
There cannot be too many links in a food chain. Food chains always begin with a plant and end with an animal. If there are more than 4 or 5 links in the chain , there will not be enough food for the animals at the end of the chain.
How are food chansand food webs different?
Food chains and food webs are different. This is because the webs have more relative food choices whereas the chains are limited.
Why the food webs are formed from food chains?
When all food chains in a habitat are joined together in some way, they form a food web. They are normally several food chains all joined up together which may include the same predator or prey in more than one food chain. hope this helps
Why does a food web tell more about an ecosystem than a food chain?
Because the food web contains2 and more food chains
Why is it more common to find short food chains than to find long food chains.?
because a food chain is based on one certain thing in the ecosystem ....if the entire ecosystem was in it it would be a food web which is food chains from an ecosystem linked together
Is there more subway restaurants than Mc Donalds?
Subway has the most food chains in the United States, but McDonald's has more locations worldwide...for now.
How many different food chains can there be?
more than 60

How do you make foodweb?
You can make an food web by joining 2 or more food Chains Together
