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

The dense haris around the flowers of the woolly lousewort are vital because they<span> trap heat from the sun. So the correct option is B. Hope this helps a lot </span>
A,
<span>Their ability to survive on other sources of energy if the required resources are not present.</span>
The presence of the minute growth near the disc signifies that the bacterial innoculum contains mutant microorganisms that are able to grow in the presence of toxic substances.
<h3>What are zones of inhibition?</h3>
The sensitivity testing in a microbiology laboratory is done to determine the effect of antibiotics on various bacteria organisms
The zone of inhibition when a disk method is used signifies the area of media where bacteria are unable to grow, due to presence of a drug that impedes their growth.
If there are presence of minute growth near the disc, it means that the bacterial innoculum contains mutant microorganisms that are able to grow in the presence of toxic substances such as disinfectants.
If these mutant bacteria organisms are not cleared by the disk method, it means that they cannot be killed by the disinfectant/antiseptics that is being tested.
