Compost is ... organic matter. Rate of ... is affected by several factors: -Temperature-> Higher increases the rate -Water availability-> Faster rate in moist places -Oxygen availability-> Oxygen for respiration -No. of ... organisms-> Fast with more

... has to be used straight away. Mainly made up of Methane which is burned as fuel. Anaerobic decay produces methane. ... is made in a generator at constant temperature
Biogas
2 of 13
Biogas production: ... generator -Small scale, manually loaded with waste
Batch
3 of 13
Biogas production: ... generator -Made all the time, large scale, produced at a constant rate and is continuously loaded with waste

... is the variety of different species of organisms on earth, or within an ecosystem. High ... is important as it maintains a stable ecosystem. Human activities are reducing ... e.g. Deforestation, Waste Production and Global Warming
Biodiversity
5 of 13
A growing population has a greater effect on the ... -> we produce more waste - if we don't properly sort waste out, we will cause more harmful pollution. We have increased our demand for natural resources so we are polluting the ... even more
Environment
6 of 13
... is where gases in the atmosphere act as an insulating layer- so the temperature increases but if not, earth would be too cold for us to survive. Greenhouse gases - Carbon Dioxide and Methane, they trap radiation increasing temperature leading to
Global Warming
7 of 13
... of Global Warming: -Melting ice caps increase sea levels -Distribution of plants and animal species changes due to temperature and rainfall patterns. -Change sin migration patterns of animals. -Reduction of Biodiversity
Consequences
8 of 13
... is the chopping down of trees for: -Clearing land for farming -Grow crops for production of biofuels. ... causes lot's of problems -Less carbon dioxide taken in by trees -More carbon dioxide in the atmosphere -Less Biodiversity
Deforestation
9 of 13
Destroying ... adds carbon dioxide to the atmosphere -> carbon is stored in them from plants that haven't fully decayed.
Peat Bogs

... of Ecosystems and Biodiversity: -Breeding programmes prevent extinction of endangered species. -Programmes to protect rare habitats -e.g. coral reefs. -Programmes to reintroduce hedgerows for habitats for wild animals
Protection
11 of 13
... of Ecosystems and Biodiversity: -Protecting biodiversity costs money -Protecting biodiversity affects local peoples lifestyles -Conflict between protecting biodiversity & protecting food security -Development is important but effects environment
