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.

∙ 12y agoThere are 3 trophic levels.
Primary Producers, who produce their own energy and organic material from inorganic substances.
Consumers, which can be classified in First Degree Consumers (herbivores) Second Degree Consumers (carnivores) and Third degree Consumers (feed off of second degree consumers)
Decomposers, who decompose and reiniciate the cicle.

Why does an energy pyramid have only three to four tropic levels?
its cool
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.
What are the five tropic levels to an ecological pyramid?
The five trophic levels in an ecological pyramid are: 1) producers (plants and other autotrophs), 2) primary consumers (herbivores that eat plants), 3) secondary consumers (carnivores that eat herbivores), 4) tertiary consumers (carnivores that eat other carnivores), and 5) decomposers (organisms that break down dead organic matter).
What is a sentence for trophic level?
The most accurate method is to use a pyramid of energy to show the transfer of energy between trophic levels
How many trophic levels are in the food chain?
There are four trophic levels in an ecological pyramid. They are primary producers, primary consumers, secondary consumers, and tertiary consumers.
Why there is a decrease of organism at each tropic level as you go up the pyramid?
No
Why is so much energy lost and where does it go in tropic levels?
In higher tropic levels, energy is lost because of the higher area of living. Metabolic activity is something else that plays a big part in the loss of energy at the tropic level.
What are the 5 levels of the tropic levels of an ecosystem?
1.Individual2.Population3.Communities4.Ecosystem5.Biome
What is the tropic hormone that is suppressed by increasing plasma levels of cortisol?
ACTH
What is the job of an energy pyramid?
Energy pyramids show relative amounts of energy which reaches from one tropic level to other.
Why is imposible to have many tropic levels?
Each tropic level is only able to use about 10% of the energy from its food. Because of this energy loss, there is usually not enough energy left to after a fourth tropic level to support anything higher.
How many tropic levels are there in the following food chain sunflowers beetle mouse?
3 (apex)
