I think for the experiment to be reliable, it must be repeated certain amount of times, roughly as many as you can, it doesnt matter whether the hypothesis is right or wrong. If the experiment is repeatedly reliable, the hypothesis might be correct.
In a food chain, only 10% of energy is transferred from one trophic level to another trophic level. If the energy produced at the producer level is 1000 J, then the energy available at the primary consumer level will be 100 J and energy available at the secondary consumer level will be 10 J.
