umka2103 [35]

Answer:

<h3>Oesophagus</h3>

Explanation:

  • The oesophagus is the region of the alimentary canal where the food passes without the absorption of nutrients. In oesophagus, we find peristaltic movement which is basically rhythmic contraction and relaxation of the oesophagus in order to facilitate the easy passage for the food to pass from mouth to stomach.
  • The oesophagus is a muscular tube which measures about 8 inches long.
  • Mucosal lining lines the oesophagus.

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.
