1) Each level losses<u> 90% </u>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).
<h3>
What is the 10% rule in trophic webs?</h3>
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<u> 90% </u>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

<span>If the PH and temperature changed significantly beyond the enzyme optimum level it will become denatured and then the enzyme would not work.
The Enzyme is a biological catalyst which speeds up a reaction. The Enzyme has molecules which act upon as substrates and then it converts those substrates into different molecules which are called products.
The study of the enzyme is known as enzymology, and they are well known to catalyze more than 5,000 biochemical reaction types.</span>
The correct answer is: Layer 1, layer 2, and layer 4 in all three regions.
The index fossils are fossils that are commonly used for identifying a geological period of time, and these fossils are also very wide spread, as well as having a rapid evolutionary trends.
By this picture, we can easily see that even though we have rock strata from different regions, the same layers contain the same fossil, and it is a fossil that also is rapidly evolving so has a minor change in each layer.
