How much energy will be converted by the primary producer to net primary productivity from 20,000 J of available sunlight energy?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 200 J
The correct answer is 200 J.
First statement: Only about 1 percent of the total sunlight that falls on producers is converted into chemical energy and stored as net primary productivity.
Reasoning:
1 percent of 20,000 J = 20,000 × 1/100 = 200 J.
Therefore, the primary producer converts 200 joules of the available sunlight into net primary productivity.
