In food chains, energy is transferred from producers to consumers between species.
Energy is used by organisms to carry out dynamic processes.
The majority of the energy in food webs comes from the sun and is turned (processed) into chemical energy by plants during the photosynthesis process.
Although energy is transferred through the food chains, it becomes less useful as trophic levels advance.
The reason for this is that only around 10% of the energy is transferred to the next trophic stage. During respiration, it is released as energy from heat.
