3. Food chains show who eats who!
Pyramids of biomass show the mass of the organisms at each stage of the
food chain.
ABCD
Which letter(s) represent the consumer(s)?
Which letter(s) represent the producer(s)?
The pyramid of biomass will always be a pyramid.
There will always be energy wastage between each stage in the
process.
Where does the energy go?
4. Energy is lost to the environment in:
Respiration energy for living eg movement
Heat – keeping warm
Waste materials – faeces and urine
5. Decay – part of the cycle of life
Organisms take energy from the environment
They also give energy to the environment when they die
Microorganisms (eg bacteria and fungus) help the decay process. These
organisms are called decomposters.
Three things will help to speed up the decay process
