Question

As we move down each level in the Linnaean Classification System, fewer organisms are showing, and there is an increase in similarities between organisms

a) true
b)false

Answer 1

The answer is true; in the Linnaean Classification System, each descending level shows fewer organisms that are more similar due to their shared characteristics and close evolutionary relationships.

Step-by-step explanation:

The student's question pertains to the Linnaean Classification System, which is a taxonomic method used to classify and organize living organisms. The correct response to the question is true as you move down each level in this system, the number of organisms in each group decreases, and the similarity among those organisms increases. This occurs because organisms are grouped together based on shared characteristics and evolutionary ancestry. The domain is the most inclusive taxonomic level, accommodating a vast diversity of life, including organisms that are markedly different from one another, such as plants, fungi, protists, and animals.

Conversely, the species level is the most exclusive, grouping together organisms that are very similar and can interbreed. As noted in Figure 20.6 and Figure 2.3.2, at each sublevel of classification, organisms are more closely related, indicating an increase in shared characteristics and a decrease in group size.
