Meg researched the biodiversity in four water ecosystems.

W - low niche diversity and warm water temperatures

X - low niche diversity and cold water temperatures

Y - high niche diversity and cold water temperatures

Z - high niche diversity and warm water temperatures

Which ecosystem likely has the highest biodiversity?

1. W

2. X

3. Y

4. Z

The correct answer is option 4. "Z".

Explanation:

A water ecosystem with high niche diversity and warm water temperatures will likely have a high biodiversity. High niche diversity refers to the presence of multiple traits in the same or different species, which is a characteristic of ecosystems with a high biodiversity. Additionally, a warm water temperature promote most species to reproduce, which also has a positive impact in biodiversity. However, temperatures above warm will affect biodiversity as oxygen is less soluble in hot waters and some species do not survive in this condition.
