The figure below shows the growth curves of two populations of Paramecium,P.aurelia and P.caudatum.From the data,we can conclude that ________.
A) the ecological niches of the two species are very different
B) P. aurelia is a predator of P. caudatum
C) P. aurelia and P. caudatum have a mutualistic relationship
D) P. aurelia is the superior competitor in this habitat

Question

The figure below shows the growth curves of two populations of Paramecium,P.aurelia and P.caudatum.From the data,we can conclude that ________. 
A) the ecological niches of the two species are very different 
B) P. aurelia is a predator of P. caudatum 
C) P. aurelia and P. caudatum have a mutualistic relationship 
D) P. aurelia is the superior competitor in this habitat

Quizplus · Accepted Answer

The growth curve of P. aurelia is higher than that of P. caudatum, suggesting that P. aurelia is the superior competitor and can outcompete P. caudatum for resources in this habitat. It does not indicate a predatory or mutualistic relationship between the two species, and the ecological niches of the two species cannot be determined based on these growth curves alone.
