4.6 Energy and substances in Food Chains

1. The producer, it is converting light energy into chemical energy.
2. This chemical energy is taking the form of organic molecules which include carbohydrates, proteins, and lipids. These molecules are food in the producer to the primary consumer. 
3. These molecules are food to the secondary consumer in the primary consumer. 
4. Finally, these food molecules are the food to the tertiary cnsumer in the secondary consumer.  
5. these molecules are composed of Carbon to hydrogen bonds, carbon to oxygen, carbon to carbon, oxygen to hydrogen, carbon to nitrogen bonds. These bonds represent energy whereas the elements represent substances.
6. The producer, while photosynthesizing, creates these organic molecules, which are the substances and contain energy.
7. Organisms use this to respire and grow.
8. These molecules are passed on along the food chain in the form of each organism in the food chain
