- Ecology
- Ecosystems
- All the organisms living in a habitat and all the non-living parts of the habitat.
- Populations: Groups of individuals of the same species.
- Communities: Made up of many populations living together.
- As well as competing with each other for food and habitat, organisms rely on each other for things like food and seed dispersal e.c.t.
- Adaptions
- Biotic factors are living factors that might affect communities. For example, availability for food and new predators.
- Abiotic factors are non-living factors that might affect communities. For example, light intensity and temperature.
- Organisms may ADAPT in a structural, behavioural or functional way.
- Organisms that live in extreme conditions are called EXTREMOPHILES. eg: Bacteria living in deep-sea vents are extremophiles
- Decomposition
- dead material is broken down by decomposers.
- They need oxygen, moisture a suitable temperature and pH to break down waste.
- Gardens provide optimum conditions for decay
- If waste is broken down in anaerobic conditions, methane gas is produced.
- Biogas generators can be used to produce biogas from waste for use as a fuel.
- dead material is broken down by decomposers.
- Recycling Materials
- The Carbon cycle describes how carbon is recycled in nature.
