How do you calculate the adjusted amount of energy that is available to organisms that are one trophic level above producers? (1 point)

Question

• gross primary productivity minus amount of organic material used in respiration
• gross primary productivity minus net primary productivity
• net primary productivity plus gross primary productivity
• net primary productivity plus amount of organic material used in respiration

Answer 1

To calculate the adjusted amount of energy available to organisms that are one trophic level above producers, you would use:

Net primary productivity.

This reflects the amount of energy that remains after producers (plants) have used some of the energy they capture through photosynthesis for their own respiration. Therefore, the answer corresponding to this concept would be:

Gross primary productivity minus amount of organic material used in respiration.

However, since the question specifies the energy available to the next trophic level, the most fitting response among the options provided is:

• gross primary productivity minus amount of organic material used in respiration.

This reflects the energy that is truly available to support the next level of consumers.
