As you move up to the food chain, the energy will decrease. This explains that the more the consumers, the lesser the energy that the last consumer will get from the sunlight. This is because each energy will decrease as it passes by the consumers because each consumers takes a portion of the full energy from the sun.
A good model would be a simple plant taking in sunlight, carbon dioxide (CO2), and water (H2O). Then, releasing glucose and oxygen.
False. Energy is never destroyed, it can only be transformed. Energy is never lost as well.
