Energy pyramid
it is a stable ecosystem
Plants are in the lowest trophic level of an ecosystem. Their level is the lowest because the needs of plants are the least complex compared to the other organisms present in an ecosystem.
it is not a stable ecosystem
A biomass pyramid.
to check its stability and health.
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.
The food web is the diagram that can be used to show the energy located at each trophic level in an ecosystem. A food chain can be used as well.

It expresses biomass at different trophic levels in an ecosystem.
A rain forest ecosystem can support 3-4 trophic levels.

Energy that is lost at each trophic level of an ecosystem is replenished by the producers. The producers get it from the sun.
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 :)
Plants are in the lowest trophic level of an ecosystem. Their level is the lowest because the needs of plants are the least complex compared to the other organisms present in an ecosystem.
