Answer:
According to the law of conservation of matter, matter is never created or destroyed but it can change from one form to another. Most of the biomass in a food web gets converted at each trophic level and it no longer remains apart of the food web. Most of the biomass is released into the atmosphere in the form of heat and hence cannot be transferred to the other trophic level. Also, matter is used up by the organism itself and converted into different forms. Most of the matter might get accumulated in the soil when the organisms of a trophic level die.
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
