The principle of competitive exclusion states that two species cannot coexist in the same habitat.
<h3>What is
competitive exclusion?</h3>
The competitive exclusion principle, often known as Gause's law, is a theory in ecology that holds that two species competing for the same scarce resource cannot coexist at constant population levels. One species will eventually outnumber all others if it has even a modest edge over the others. This results in the weaker competitor's extinction or an evolutionary or behavioral shift in favor of a different ecological niche. The adage "complete competitors cannot coexist" is a paraphrasing of this idea.
Although he never created it, Georgy Gause is traditionally credited with coming up with the competitive exclusion principle. The natural selection theory put forward by Charles Darwin already incorporates the concept.
The status of the principle has fluctuated during the course of its history between

The correct answer would be that substance A is rice, and substance B is sugar.
For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.
Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.
Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.
