The actual niche the organism is able to occupy in the presence of competitors is called its:_____________.
ladessa [460]

Answer:

B) realized niche

Explanation:  

The ecological niche refers to all the environmental factors that influence the growth, survival, and reproduction of species. These factors also include the interaction between species. The term ecological niche refers to the fundamental niche or the realized niche.    

  • The fundamental niche refers<u> only</u> to factors or physical conditions under which a species can live and survive in the <u>absence of any interaction with other species. </u>
  • The realized niche refers to the restricted conditions in which a species can live and survive as a result of <u>environmental conditions and the interaction with other species</u><u>. </u>

When an inferior competitor is excluded by the superior competitor, this is known as competitive exclusion. This occurs when there is not habitat differentiation, and both species can not share the same niche. In this case, the effective or realized niche of the dominant species completely occupies the fundamental niche of the inferior competitor.        

 In the exposed example the organism is able to occupy a niche in the presence of competitors, which is the clue for us to classify this niche as a realized niche. The organism needs to interact in a certain way with its competitors. There is an interaction between taxonomic groups, or between individuals.

During glycolysis, glucose is broken down into two molecules of pyruvate. What is the main transformation that occurs during gly
mr_godi [17]

Answer;

-Glycolysis produces pyruvate, ATP, and NADH by oxidizing glucose

Explanation;

-Glycolysis is the first of the main metabolic pathways of cellular respiration to produce energy in the form of ATP. Glucose is cleaved or broken down into two three-carbon sugars of pyruvate through a series of enzymatic reactions.

-Overall, the process of glycolysis produces a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules for the cell to use for energy. Following the conversion of glucose to pyruvate, the glycolytic pathway is linked to the Krebs Cycle, where further ATP will be produced for the cell’s energy needs.
