 Reduced weight changes of symbiotized and albino anemones 

 starved in light and darkness are depicted in Figure 3, and expressed 

 as percent change from initial weight vs. time in weeks. The results 

 show that durmg starvation all anemones lost weight at a near con- 

 stant rate, and that symbiotized anemones lost weight at about half 

 the rate of albinos. The possiliility tliat light could have directly
