Want this question answered?
"Trophic" is directly related to bio-physical shape. So the lowest trophic levels will reflect those Organisms that do not have much shape - worms, slugs, fungi, molds and bacteria.
Quaternary consumers
producers (autotrophs)are the sole point from which the energy enters into the earth and ecosystem and the one way flow of energy takes place when food travels between different trophic levels...
Coniferous trees reproduce by cones, so you'll see pinecones on them instead of fruit or flowers. In other respects they look like normal trees.
Which one is best ?a)Yes, but only if the extra food was sent to countries with starving people. b)Yes, because it would decrease environmental degradation. c)I don't eat meat now. d)No, I don't see the need to eat lower on the food chain. e)No, I like the taste of meat too much.
A rain forest ecosystem can support 3-4 trophic levels.

it can be A)The ecosystem will not be able to support as many tertiary consumers. B)It will decrease the amount of energy transferred to higher trophic levels. C)The ecosystem will be able to support more organisms at higher trophic levels.Eliminate D)The ecosystem will become stagnant due to excess producers and organisms in higher trophic levels will die out.
it is a stable ecosystem
Energy that is lost at each trophic level of an ecosystem is replenished by the producers. The producers get it from the sun.
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 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.

producers- plants
