Well the trophic model is like the pyramid (Food Chain).
But the difference is that trophic model's change every time you go to a different ecosystem.
(Ecosystem Definition - http://dictionary.reference.com/browse/ecosystem)
Pristine Ecosystems have a wine shaped trophic model and Near - Pristine Ecosystems have a upside down wine shaped trophic model. Human affected ecosystems have a triangle trophic model.
What else can I help you with?
What is bottom up model?
The bottom-up model postulates a unidirectional influence from lower to higher trophic levels.
What model shows the amount of energy lost during transference between trophic levels?
Food Web
What trophic level is a quail in?
The first trophic leval

What trophic level is a salamander?

What is the hawks trophic level?
they are tertiary consumers. the first trophic level.
what are the trophic level for monarch butterflies?
Their trophic level is primary consumer.
How are trophic level efficiency measured?
Trophic level efficiency is typically measured by calculating the amount of energy transferred from one trophic level to the next. This is done by analyzing the ratio of energy present in the biomass of one trophic level compared to the trophic level below it. The efficiency of energy transfer between trophic levels is usually around 10%, meaning that only around 10% of energy is transferred from one trophic level to the next.
Why does productivity diminish with increase trophic levels?
Due to poor trophic transfer efficiency, most energy is lost at higher trophic levels.
Organisms at the first trophic level are called?
Producers make up the first trophic level. A trophic level is each step in a food chain or food web is called a trophic level.
