Biologists use their observations on a small island to construct the food web shown. Their calculations indicate that the produc

Lelechka [254]

The flow of energy from one level to another does not happen with 100% efficiency. The producers only transfer 10% of the energy they absorb from the Sun. The major chunk of the absorbed energy goes into the growth of the producers, the rest gets lost in the form of waste (shedding of leaves, reproduction, etc.) and the remaining 10% is the amount that is available to the primary consumers. So by this logic, if there is 150,000 KJ of energy available at the producer level, then, only 15,000 KJ of energy will get transferred to the primary consumers.

Answer:

cumulative dilution = 0.000001

Explanation:

A serial dilution is a stepwise kind of dilution repeated a certain number of times, in which the concentration reduces exponentially each time.

The cumulative dilution is the final dilution gotten depending on the number of times dilution has been done and the dilution factor. The formula is given as:

Cumulative dilution = (F)ⁿ

where:

F = dilution factor = 0.1

n = number of serial dilutions = 6

∴ cumulative dilution = (0.1)⁶ = 0.000001

3. "Propitiatory" is another word used to describe something that is like a conciliatory offering, a token of appeasement, or trying to please someone or something. In the given sentence, it is used to describe how she will be offering a conciliatory act to him.

4. The word "propitious" is synonymous with something favorable, advantageous, presenting a promising idea. And in its use, the sentence presents how the public distress is favorable for Tom Walker to set up his office.
