Food chains can't go on forever because each consumer is only able to receive 10 percent of the energy that the plant that was eaten had. There are also only so many animals that are able to eat other animals.
A common metric used to quantify food web trophic structure is food chain length. Food chain length is another way of describing food webs as a measure of the number of species encountered as energy or nutrients move from the plants to top predators. There are different ways of calculating food chain length depending on what parameters of the food web dynamic are being considered: connectance, energy, or interaction.In its simplest form, the length of a chain is the number of links between a trophic consumer and the base of the web. The mean chain length of an entire web is the arithmetic average of the lengths of all chains in a food web.
In a simple predator-prey example, a deer is one step removed from the plants it eats (chain length = 1) and a wolf that eats the deer is two steps removed (chain length = 2). The relative amount or strength of influence that these parameters have on the food web address questions about:

A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition. A food chain starts with the primary energy source, usually the sun or boiling-hot deep sea vents. The next link in the chain is an organism that make its own food from the primary energy source -- an example is photosynthetic plants that make their own food from sunlight (using a process called photosynthesis) and chemosynthetic bacteria that make their food energy from chemicals in hydrothermal vents. These are called autotrophs or primary producers.
The food chain is called a chain because each organism is like a link in a chain, with each link attached to the next link which is attached to the next.

If decomposers were not t the end of all food chains then the food chains would not be able to work. This is because the nutrients would not be returned to the producers.
Thank you for reading my essay. The End.

food chains that overlap I think are called overlapping food chains. Food chains that overlap are called overlapping food chains.
Because no one eats humans, ostensibly.
Some people think food chains will never end , otherwise all humans and animals will die.
No because a food chain ends with an animal eating another animal
Efficiency decreases as length of food chain increase as little foo is available at end of food chain .
They are called food chains.

Food Chains! :)
