20 What is the best explanation for why there are no organisms represented by the white circles after the “natural event”?

Answer 1

The best explanation is that the natural event likely caused environmental conditions that were unsuitable for the organisms represented by the white circles to survive or thrive. This could include factors such as lack of food, shelter, or suitable habitat, as well as potential effects like habitat destruction or pollution. These unfavorable conditions may have led to the absence of organisms represented by the white circles in the post-event scenario.
