So the area is 2x3 cm with 68 paramecia.
Not sure if this is the best way to do it, but I’d do 68/2*3 (68 divided by (2 times 3))
So first 2*3 is 6cm.
Now you’re trying to find paramecia/cm2. You are trying to find a unit rate. That is a value over one.
Then because there are 68p and 6cm, to find the unit rate, you’d do 68/6.
Now you have your unit rate, which is 11.3 repeating, or 11 1/3 as a fraction.
That would be 11.3 (11 1/3) paramecia per cm2
also I’m not 100% sure if this is correct, just wanted to help, so no guarantees
All starfish limbs are designed to do have the same function, which means that in case a limb is severed, the other arms can make up for it until the arm regrows, which it does after a while. They are all connected to the center of the starfish which should not be damaged.
Answer:
For a approximate answer, you need the speed of the s-wave which is not in the question, to find the time.

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).

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
