How do you calculate the adjusted amount of energy that is available to organisms that are one trophic level above producers
1. gross primary productivity minus amount of organic material used in respiration
2. increases
3. by observing cellular respiration under the absence of light
4. dead organisms and waste are recycled throughout the trophic levels.
5. the rate that plants and other photosynthetic organisms produce organic compounds.

The adjusted amount of energy available to organisms one trophic level above producers can be calculated by subtracting the energy lost in the form of respiration and metabolic waste from the total energy produced by the producers. This adjusted energy is then available to the organisms at the next trophic level.
100 %
To calculate the adjusted amount of energy available to organisms one trophic level above producers, we can use the concept of ecological efficiency and the 10% rule.
The 10% rule states that only about 10% of the energy from one trophic level is transferred to the next trophic level. This means that each trophic level receives only 10% of the energy available from the previous level.
To calculate the adjusted amount of energy, follow these steps:
1. Determine the total amount of energy available at the producer level. This can be done by collecting data on the primary productivity of the ecosystem, which measures the rate at which producers convert sunlight into organic compounds through photosynthesis.
2. Multiply the total energy available at the producer level by 10% (0.1) to calculate the amount of energy transferred to the next trophic level. This represents the energy available to organisms one trophic level above producers.
For example, if the total energy available at the producer level is 10,000 kilocalories (kcal), the energy available to organisms one trophic level above producers would be:
Energy available to organisms one trophic level above producers = 10,000 kcal * 0.1 = 1,000 kcal
Therefore, in this example, organisms one trophic level above producers would have 1,000 kilocalories of energy available to them.
