1. Compare the structure of the two island groups' ecosystems. First, calculate the average fish biomass in each trophic level for each island group. Then use these values to draw
biomass pyramids on graph paper. Draw the pyramids so that the levels are proportional
to the data. (Hint: Draw the smallest level first.)

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
