Biologists also refer to carrying capacity as the “maximum load”. Carrying capacity has factors it depends on. These are the many abiotic and biotic factors in the ecosystem and some are more obvious than others.  The most obvious being, the availability of the basic needs of organisms which make up the different ecosystems. Some of these are food, water and shelter in which dictate how many individuals the ecosystem can sustain.

kobusy [5.1K]

Answer:

A). The model does not predict energy flow.

Explanation:

As per the given details, the most probable constraint of using 'numerical computer-built models' would be their 'inability to forecast the energy that is flowing throughout the ecosystem.' However, they assist in offering collected information at the same time yet <u>its failure to predict the actual amount of energy flowing that will lead to a failure to predict if the ecological balance is being maintained or not</u>. As a result, some organisms may be deprived of the appropriate food to ensure their survival and their existence on this planet might be under threat. Thus, this is the limitation of using such-technology based models and hence, <u>option A</u> is the correct answer.

It is most likely due to the fact that the attenuation is the evolutionary relic, which by accident has remained does not support the actual reason of the dual control to regulate the operon.

Answer: Option E

<u>Explanation:</u>

In bacteria transcription and translation carries out at the same time so or the termination of transcription in premature phase in bacteria uses a special mechanism which is called as attenuation T.

he attenuation in bacteria is a regulatory mechanism. Trp operon is the group of codes of the components. These operons are the actual functioning group of the DNA.
