evious Ans This graph illustrates the number of marine families identified in the fossil record from 600 million years ago to the present day. Black circles represent the dates of mass extinction events Correct Unlike many graphs, on this graph, the values on the x-axis decrease from left to right, so reading information at the right spot can be tricky. Use the graph to answer the question s. g 800 Mass extinctions 600 Part B Thinking critically 400 Select the three statements that are supported by the data in this graph 200 The presence of a large number of families in marine ecosystems protects against mass extinction events Mass extinction events occur at regular, predictable intervals Most mass extinction events have resulted in the loss of about Z 600 400 300 200 500 100 Present Millions of years ago 20% of marine families The time required for marine family diversity to recover after mass extinction is about 10 million years Diversity in marine families more than doubled between 500 and 450 million years ago Submit Request Answer

Explanation / Answer

Based upon the inormation provided in the graph the following three statements are supported by the data in the graph

1 The presence of a large number o families in marine ecosystem protects against mass exitinction events

2 Mass exitinction events occurs at regular predictable intervals
