Question

What is not true about species turnover rate?

a. The rate at which species replace each other
b. High rate means species composition is fluid
c. Larger areas have greater compositional stability
d. All of the above are true

Answer 1

Species turnover rate refers to the rate at which species replace each other in a community. High turnover rate means species composition is fluid. Larger areas do not have greater compositional stability when it comes to species turnover rate.

Step-by-step explanation:

Species turnover rate refers to the rate at which species replace each other in a community. It is a measure of the change in species composition over time. The options given are:

1. The rate at which species replace each other - This is true.
2. High rate means species composition is fluid - This is also true. A high turnover rate indicates that species are being replaced quickly, leading to a more fluid composition.
3. Larger areas have greater compositional stability - This statement is false. Larger areas tend to have higher turnover rates because there are more opportunities for different species to colonize and replace each other.

Therefore, the correct answer is c. Larger areas have greater compositional stability.
