1) Each level losses 90% of energy that was contained in the previous level. 2)Protozoa (Producer), snail, shrimp, amphipods (Primary consumers), Salamander (Secondary consumer), Intestinal roundworm (Tertiary consumer), fungi (Decomposer).
What is the 10% rule in trophic webs?
The 10% rule states that at each trophic level occurs an energy transference from one of the levels to the next, with only 10% being usable in each of them.
As a general rule, only about 10% of the energy stored as biomass at one trophic level -per unit time- ends up as biomass at the next trophic level -in the same unit of time.
The remaining 90% of energy is lost to the environment as heat.
The progressive reduction of energy determines the number of trophic levels (4 or 5).
In the xposed example,
1) Each level losses 90% of energy that was contained in the previous level.
2)
- 1st level: Protozoa ⇒ Producer
- 2nd level: snail, shrimp, amphipods ⇒ Primary consumer
- 3rd level: Salamander ⇒ Secondary consumer
- 4th level: Intestinal roundworm ⇒ Tertiary consumer
- 5th level: fungi ⇒ Decomposer
