Question

what can you conclude about species abundance and diversity in the peril river watershed area? a. species abundance and diversity have increased. b. species diversity has increased but abundance has decreased. c. species diversity and abundance have both decreased. d. species diversity and abundance have remained consistent. choose your answer below!

Explanation:

To answer this, we analyze the options. In typical ecological scenarios (e.g., improved environmental conditions in a watershed), species abundance (number of individuals) and diversity (number of species) often increase. Option A aligns with this, as options B (abundance decrease is unlikely with diversity increase in a healthy watershed), C (both decreasing would imply degradation), and D (remaining consistent is rare without stable, unchanging conditions) are less likely.

Answer:

A. Species abundance and diversity have increased.
