Answer 1

Based on your statement about the graph, the correct phrases to fill in the blanks would likely be:

1. "decreases" during a mass extinction event and then
2. "recovers" after the event.

So, the full statement would read:

"Based on the graph, biodiversity decreases during a mass extinction event and then recovers after the event. In general, biodiversity on Earth increases over time."

If you have a specific graph in mind, the details might differ slightly, but this is a common trend observed during and after mass extinction events.
