How is energy transferred from the sun, then cycled through all living organisms in an ecosystem?

I guess this the answer

Energy and nutrients are passed around through the food chain, when one organism eats another organism. So first plants absorb sunlight and then other organisms (herbivores) eat plants and then other organisms feed on those and so on

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
