Answer:
Quorum sensing is triggered to begin when<u> a sufficient number of bacteria are present .</u>
Explanation:
Quorum sensing -
Quorum sensing is the ability to detect and to respond to the cell population density by the process of gene regulation . Quorum sensing bacteria releases some chemical signal molecules called the autoinducers , that increases the concentration as the function of the cell density .
The detection of the minimum threshold concentration of an autoinducer leads to the alteration in the gene expression .
The action that may increase the flask's carrying capacity for rotifers would be to decrease the number of microorganisms in the flask.
<h3>Carrying capacity</h3>
The carrying capacity of an environment refers to the maximum number of organisms of a particular species that the environment can support based on the resources it has.
Rotifers and microbes growing in the flask mean that both species would have to compete for the resources present in the flask. This competition will limit the reproductive capacity of each species.
As the population of the species decreases, the growth of the other is favored due to less competition.
With rotifers growing alone in the flask, there would be less competition for resources and more population growth.

Answer:
b. They are on trophic levels 3–5
Explanation:
The trophic level of an organism represents its position within the food web in an ecosystem.
A food web is defined as a system of interlocking food chains within an ecosystem while food chain in itself is defined as a chain or sequence of transfer of food from one organism to another in an ecosystem.
<em>The first trophic level in a food web contains the producer.</em>
<em>The second trophic level contains the secondary primary consumers.</em>
<em>The third trophic level contains the secondary consumers.</em>
<em>The fourth trophic level contains the tertiary consumers.</em>
<em>The fifth trophic level contains the quaternary consumers.</em>
Small fishes eat producers, primary consumers as well as insects which are secondary consumers while they themselves are eaten by adult largemouth bass.
That small fishes eat producers successfully place them at a minimum level of trophic level two (primary consumer). Feeding on primary consumers means that they can also be at trophic level three (secondary consumer) while feeding on secondary consumers means they can also be at trophic level four as tertiary consumer.
<em>Since adult largemouth do not feed directly on producers, it means their minimum trophic level is three (secondary consumer) and since they feed on smaller fish, it means their maximum level is five (quaternary consumer).</em>
The correct option is b.
