Why do most food chains do not extend beyond the 4 th trophic level?

The amount of energy transferred from each trophic level to the next is around 10%. This is a tiny amount. By the 4th level, there is so little energy available that it is not possible (in most cases) to support a 5th level. Generally, where a 5th level exists, the organism isn't on the 5th level for every chain it is included in. Example:
Primary producer (1st level) :100 Joules
Primary consumer (2nd level) : 10 J
Secondary consumer (3rd level) : 1 J
Tertiary consumer (4th level) : 0.1 J

What is an example of a food chain with a plant?
Most, if not all, food chains have a plant of some sort in it - around trophic level one.
How are trophic level efficiency measured?
Trophic level efficiency is the ratio of production of one trophic level to the production of the next lower trophic level. This efficiency is never high.
In ecology green plants are part of what trophic level?
The first trophic level, which are the producers
What trophic level is at the bottom in Biology?
Primary producers are the bottom most trophic level.
What animal would be at the 2nd trophic level?
The group of organisms that occupy the second trophic level of an ecosystem is the herbivores. The herbivores eat the plants in the first trophic level and are then called primary consumers. -Gallo :)
In food chains why do the arrows flow from the bottom upwards?
The energy is transferred from a lower trophic level to a higher trophic level when resources are consumed.
What are the differences between food web and trophic levels?
Food webs are made from many food chains. A trophic level in every food chain is a stage where energy is transferred from a lower level to the next higher level. Trophic levels include producers, consumers (primary and secondary), decomposers.
What roles do trophic levels play in the transfer of energy within food chains and food webs?
Trophic levels play a significant role in the transfer of energy within food chains and food webs. Each organism has a position n the trophic level and energy is transferred through succession.
What is an example of a food chain with a plant?
Most, if not all, food chains have a plant of some sort in it - around trophic level one.
What trophic level are scavengers?
Scavengers are on every trophic level
What is the trophic level of the bird?
The trophic level is where an organism falls on the food chain. Most birds fall on the highest level, trophic level 4.
What is a level or feeding group called in a food chain?
Most chains have links so I would say that each step is called a link.
What is the hawks trophic level?
they are tertiary consumers. the first trophic level.
What trophic level is a salamander?
Third trophic level. It eats insects.
what are the trophic level for monarch butterflies?
Their trophic level is primary consumer.
Animals that feed on plants are in what trophic level?
In which trophic level are all plants found?
What is efficiency level?
Trophic level efficiency is the ratio of production of one trophic level to the production of the next lower trophic level. This efficiency is never high.
