Chapter 4 Critical Thinking

1.) During the day, algae carry out both photosynthesis and respiration, but at night, whent here is no light, they can only perform respiration. Small, isolate4d tide pools on rock shores are often inhabited by thick growths of seaweeds, which are algae. Would you expect the amount of oxygen in the water to differ between night and day? How?

--> Yes i would expext the aount of oxygen to decrease or lessen at night because without solar energy autotrophs do not produce oxygen.
