- Energy flow
- most ecosystems rely on a supply of energy from sunlight
- autotrophs
- cyanobacteria
- producers
- plants
- algae

- heterotrophs
- autotrophs
- light energy is converted to chemical energy in carbon compounds by photosynthesys
- chemical energy in carbon compounds flows through food chains by means of feeding
- the arrow in a food chain indicates the direction of energy flow
- energy released by respiration is used in living organisms and converted to heat
- synthetise large molecuels
- ATP
- active transport
- ATP
- moving things around the cells
- not all of the energy is transferred
- synthetise large molecuels
- Living organisms cannot convert heat to other forms of energy
- light energy - chemical energy
- chemical energy - kinetic energy
- chemical energy - electrical energy
- chemical energy to heat energy
- Heat is lost from ecosystems
- energy losses between trophic levels restrict the length of food chains and the biomass of higher trophic levels
- only 10% is passed to the next trophic level
- most ecosystems rely on a supply of energy from sunlight
