- Environment
- Measuring environmental change
- Measured using living indicators
- Some organisms are very sensitive to environmental change - living indicators
- Air pollution - lichen
- Raw sewage - bacteria take up oxygen - less mayfly
- Also measured by non-living indicators
- Satellites measure temperatureof the surface of the sea and amount of snow
- Automatic weather stations - atmospheric temperature
- Rainfall - rain gauges
- Dissolved oxygen meters - water pollution change
- Measured using living indicators
- Energy transfer and decay
- The sun's energy
- Source of nearly all life on Earth
- Green plants and algae use a small percentage for photosynthesis
- Energy makes it's way through food chain
- Respiration supplies energy for all life processes
- Most energy lost as heat
- Some materials in animals and plants are inedible
- Don't pass energy in food chain
- Energy lost as waste material
- Why food chains don't have more than five levels - energy is lost
- Don't pass energy in food chain
- Elements cycle in the food chain because of decay
- Living things take materials from the world
- Plants turn carbon etc. into complex material
- Elemets rturned as organisms die or as their waste products
- Elements decayed by microorganisms - back in soil
- Microorganisms work best in warm conditions and with lots of oxygen like compost bins
- In stable communities the cycle is balanced
- The sun's energy
- The carbon cycle
- How Carbon is recycled (CO2 IN AIR)
- Carbon compounds in plants
- Respiration
- Carbon compounds in animals
- Respiration
- Animals eat plants
- Carbon compounds in plants
- Respiration
- Carbon compounds in plants
- Animals death and waste goes into soil
- Carbon compounds in the soil being decayed by microorganisms
- CO2 released from decay
- Carbon compounds in the soil being decayed by microorganisms
- Products made from plants and animals
- Burn
- Fossil fuels
- Burn
- Carbon compounds in the soil being decayed by microorganisms
- CO2 released from decay
- WHOLE THING IS POWERED BY PHOTOSYNTHESIS
- Carbon compounds in plants
- How Carbon is recycled (CO2 IN AIR)
