Based on the information in Table 1 and Figure 1, what is the most likely explanation for the difference in net productivity between 16 successional years and 64 successional years?

• More productive small trees become dominant.

• Less productive weeds become dominant.

• Shrubs continue to be dominant.

• Less productive grasses become dominant.

A scientist theorized that in general, plants and animals with a higher combined net productivity appear later in an area than plants and animals with a lower productivity. What evidence from Table 1 and Figure 1 supports this theory?

• Canopy trees are the last to appear in Table 1.

• As time goes on in Figure 1, net productivity decreases.

• As time goes on in Figure 1, net productivity increases.

• The straw-necked ibis does not appear until 35 years have passed.

• The quail no longer appears in the ecosystem once shrubs become dominant.

• The quail does not appear in the ecosystem at the same time as the friarbird.
