Answer

Image with description A bar graph titled “Threats to Biodiversity” with percent of total extinctions on the vertical axis and causes on the horizontal axis. The bars show introduced species about 39 percent, habitat loss about 36 percent, hunting and poaching about 23 percent, and other about 2 percent.

Image with description A bar graph titled “Threats to Biodiversity” with percent of total extinctions on the vertical axis and causes on the horizontal axis. The bars show introduced species about 39 percent, habitat loss about 36 percent, and a combined category of hunting, poaching, and other at about 25 percent.

Image with description A bar graph titled “Threats to Biodiversity” with percent of total extinctions on the vertical axis and causes on the horizontal axis. The bars show introduced species about 40 percent, habitat loss about 40 percent, and hunting and poaching about 20 percent, with no separate bar for other.

Explanation

The graph should show each cause as a separate category with the percentages given: introduced species 39%, habitat loss 36%, hunting and poaching 23%, and other 2%. Choice A matches all four categories and values. Choice B combines categories, while C swaps the habitat loss and hunting percentages, and D rounds and omits the separate “other” category.
