The average amount of energy transferred from one trophic level to the next is 10%. For example, 10% of the solar energy that is captured by phytoplankton gets passed on to zooplankton (primary consumers). Ten percent of that energy (10% of 10%, which is 1%) gets passed on to the organisms (secondary consumers) that eat the zooplankton.
Explanation:
Energy transfer in and between organisms. Within the food chain energy can be passed and transferred from one organism to another. Whilst mammals get their energy sources from food – whether this be eating other animals or eating vegetation; plants get their energy from photosynthesis.

Answer: unreliability
Explanation: Some of the problems that determine the quality of an experiment are reliability and validity.
Reliability considers the consistency of the experiment. In the example above, the result of the second sample is inconsistent with the result of the first sample, making Watt's research unreliable. That is, it does not reflect the ratings of a larger population. This problem can be solved by increasing the sample size, such that the average ratings are more reflective of a wider audience.
Validity considers the accuracy of the experiment. A lack of reliability of an experiment will likely make the result invalid as well, but this is not always the case.
