- Energy of Biomass
- Pyramids of biomass
- Biomass is thr mass of living materials in plants and animals
- Radiation from the sun is the main source of energy for living organisms
- Green plants and algae capture light energy during photosynthesis
- The biomass at each stage in a food chain is less than at the previous stage.
- Green plants transfer solar energy to chemical energy which is then passed through the food chain
- Energy Transfer
- There is less biomass and energy available at each stage in a food chain
- Materials are used at each stage and energy may be transferred to the surroundings
- Much of the energy is released in resporation
- Decay Processes
- living organisms remove materials from the enviroment which are returned when the organism dies.
- Microorganisms decay waste and dead plants and animals
- Devay is quicker in warm, moise aerobic conditions
- Processes which use materials must be balanced by those which release them
- Detritus Feeders ( such as some type of worm) may start the process of decay by eating dead animals or plants and produce waste materials
- humans recycle waste in sewage treatment plants and compost heaps
- The Carbon Cycle
- The constant cycle of carbon in nature.
- During photosynthesis, carbon dioxide is removed from the atmosphere
- Recycling organic waste
- Recycling organic Kitchen or Garden waste is neccessary to : Recduce landfill, reduce methane production, recycle materials and nutrients in the wate
