Energy
- Pyramids of Biomass
- Trophic Levels
- A feeding level
- Less energy and
biomass at each level
- Fewer organisms each
time you move up
- A feeding level
- Mass of living material at
each stage of the food chain
- (bottom to top)Producer, primary consumer,
secondary consumer, tertiary consumer
- Trophic Levels
- Energy in Food Chains
- Energy comes
from the sun
- Plants use the suns
energy for photosynthesis
- Respiration provides energy.
It is lost by heat and waste
- Some animals/plants have inedible
plants, so energy is not passed on

- Plants use the suns

- Energy Loss Causes
- Movement
- Heat loss from respiration
- Heating Bogy
- Faeces and Urine
- Growth and Repair

- The Carbon Cycle
- Photsynthesis removes
CO2 from the air
- Plants and animals
respire
- Plants and animals die, detritus
fedders eat them, they respire
- Waste and dead
organisms taken up in soil
- CO2 is back in the air
- CO2 is back in the air
- Fossil fuels are
burnt
- Plants and animals
respire
- Photsynthesis removes
CO2 from the air
- Decay Processes
- Plants take elements (carbon, oxygen,
hydrogen, nitrogen), from soil or air
- Elements turned into complex
compounds, passed through food chain
- They return to the environment in
waste products, they decay because
they're broken down by migroorganisms
- Microorganisms work best in warm, moist
conditions and with plenty of oxygen
- Elements are recycled
in compost bins
- Put into the food
chain again
