Answer:
TRUE
Explanation:
The trees are the primary producers that produces the food on which the consumers are dependent. This forms the base of the ecological pyramid for both energy as well as biomass.
In any biological condition, it can be observed that during its ecological succession from one trophic level to the next, almost 90% of its total energy is lost, and only 10% of its energy is transferred to the successive trophic level.
Similarly, biomass is also comparatively higher in producers like plants and trees than in any other trophic levels.
Thus, the given statement is True.
The probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade is: D. 0.80.
<h3>How to calculate the probability?</h3>
In this exercise, you're required to determine the probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade. Thus, we would apply Bayes's theorem.
- Let S represent studied for.
- Let B represent a score of B or higher grade
Therefore, we need to find P(S|B):

S|B = 0.80.

<u>Complete Question:</u>
At the beginning of the semester, a professor tells students that if they study for the tests, then there is a 55% chance they will get a B or higher on the tests. If they do not study, there is a 20% chance that they will get a B or higher on the tests. The professor knows from prior surveys that 60% of students study for the tests. The probabilities are displayed in the tree diagram.
All of the aforementioned are implied by Viagra advertisements except that: women should be more se-xually assertive.
<h3>What is an advertisement?</h3>
An advertisement can be defined as consumer promotions programs that are designed and developed with the sole intention of making the various goods (products) or services which are being offered by a business firm to become known, popular and familiar to all of its customers and potential customers.
In this scenario, we can infer and logically that Viagra advertisements which depicts it as being an aphrodisiac and se-xual enhancer doesn't imply that women should be more se-xually assertive over their male counterparts (partners).
