4.6 Energy and substances in food chains

- Bushgrass eaten by impala - Bushgrass is the producer, Impala is the primary consumer, leopard is the secondary consumer, lion is the tertiary
- producer turns light energy into chemical energy - takes the form of organic molecules including carbohydrates, proteins and lipids --> what we call food
- These molecules are composed of C-H bonds, C-O bonds, C-C bonds, O-H bonds and C-N bonds - ALL represent energy
- C H O N are the substances/matter - contain the energy from the sunlight
- Impala consumes this for growth and respiration and life processes - then the leopard consumes the impala passing on the same molecules, reorganizes them into leopard form and then to the lion who reorganizes them as well
- What is passing is the 'matter' and energy (in the bonds)

These molecules are composed of C-H bonds, C-O bonds, C-C bonds, O-H bonds and C-N bonds - ALL represent energy.
