The number is limited by the amount of energy lost at each trophic level. Most cannot exceed 5.

Number of trophic levels in ecological pyramid?
there can be any number of trophic levels, but usually 4-5
What are the 4 kinds of ecological pyramind?
The first of the four, is the ecological pyramid. It shows the number of organisms in each of the trophic levels in an ecosystem. At the base of the levels are the producers and at the top of the pyramid are the final consumers. The second is the number pyramid. This also shows the number of organisms in each of the trophic levels but it does not take into consideration the size of each of the organism in the levels. This pyramid has four levels, starting from the bottom is the total number of producers, then the total number of herbivores, third the total number of small carnivores, and finally the total number of large carnivores. The third pyramid is the biomass pyramid. This pyramid is an indication of the total mass of organisms in the trophic levels. There are three levels of biomass in this pyramid. These are producers ( 470.0 g/m2), then herbivores (0.6 g/m2), and last the carnivores ( 0.1 g/m2). And it is possible for the second level to be greater than the third. Last, is the energy pyramid which indicates the total amount of energy that is in the trophic levels. It also is able to show the loss of energy between the trophic levels. The four levels in this pyramid are Producers, Primary consumers, Secondary consumers and at the top are the Tertiary consumers. As energy passes between the levels, such as from producers to primary consumers, much of the energy is lost due to waste and the conversion to heat energy.
Whats the difference between biomass pyramid and energy pyramid and number pyramid?
== == Of the trophic levels of the ecological pyramid, there are three ways to describe the flow of energy in food chains. Numbers, energy and biomass. See the related link for more information.
What model shows the number of organisms at each tropic level in an ecosystem?
The major types of ecological pyramids are a pyramid of numbers or biomass or energy.The pyramid of numbers depicts the number of individual organisms at different trophic levels of food chain. Successive links of trophic structure decrease rapidly in number until there are very few carnivores at the top.In many ecological pyramids, the producers form the base and the successive trophic levels make up the apex. The apex is a term meaning pointed top.Energy pyramids are always slopping because less energy is transferred from each level than was paid into it.
The number of tropic levels in an ecological pyramid?
ECOLOGICAL food chains are typically short, consisting of not more than four or five trophic levels. This is usually explained by a reduction in the energy which is available to successive links in the food chain1,2. In contrast, we believe that the number of trophic levels is constrained by population dynamics and not by ecological energetics.
What does each type of ecological pyramid depict?
An ecological pyramid is simply a graphical representation of the relationship at each trophic level in a particular ecosystem. There are three types of ecological pyramids: of numbers, of energy, and of biomass. For example the pyramid of numbers is a representation of the number of organisms in each trophic level, with herbivores at the bottom as primary consumers, followed by first level carnivores and so on.
Which type of diagram shows the number of trophic levels an ecosystem supports?
A biomass pyramid.
Most ecosystems can be visualized as a pyramid with many organisms in the lowest trophic levels and only a few individuals at the top Give an example of an inverted numbers pyramid?
An example of an inverted numbers pyramid can be seen in a parasite-host relationship, where a single host may support a large population of parasites. In this case, the number of individuals in the higher trophic level (parasites) exceeds the number of individuals in the lower trophic level (host).
How are energy pyramids and trophic level alike?
The trophic levels show which organisms are at each level of the energy pyramid. The pyramid is shaped exactly as a pyramid. The lowest level contains the most energy and the most in number and variation of species. The next level only has 10% of the first levels' energy and fewer species. The amount of energy in the first level determines the number of levels possible. The tropical rain forest has the most levels (as many as 4) and a desert has the fewest (as few as 2).

What does a number pyramid tell you about an ecosystem?
Shows the relative number of individual organisms at each trophic level.
What are the concept of an ecological pyramid?
The ecological pyramid is basically the food chain. So, the producers (plants) are at the bottom, then herbivores (plant eaters), then above them are the omnivores or carnivores, and then the most powerful and top of the food chain animals are at the top of the pyramid.
What relationship exists between trophic levels and food chain?
Trophic levels and food chains are connected in number of ways. Trophic levels show the energy transfer throughout the species in different food chains.
