- energy loss along a food chain
- plants convert less than 3% of sunlight into chemical energy
- falls on non- photosynthesising surfaces
- reflected
- passes through
- in the energy transfer from carbs
- energy losses in the consumption of producers
- not all the plant is eaten
- not all materials can be fully digested
- energy lost as heat in the consumers digestive system as molecules are hydrolysed
- productivity
- rate of which plants convert light energy into chemical potential energy
- gross primary productivity
- total quantity of energy transferred
- net primary productivity
- energy that is left as chemical energy after the plants have supplied there own needs by respiration
- ways to increase photosynthetic efficiency
- plant closer together
- more water
- extra mineral ions as fertilisers
- plants convert less than 3% of sunlight into chemical energy
