answer
1955 to 1970
question
Choose the likeliest explanation for the trend shown in the graph in step 2.
answer
Most potential fisheries in the world's oceans had been discovered by about 1970.
question
Compensation depth is the depth in the ocean where the photosynthetic rate exceeds the rate of cellular respiration.
answer
False
question
The products of photosynthesis are carbon dioxide (CO2) and water (H20).
answer
