  • 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.
    • Recycling Materials
      • The Carbon cycle describes how carbon is recycled in nature.

It turned out to be a very cool scheme, I used it in writing my term paper, besides environmental issues, I am also fond of playing in a Canadian online casino https://casinocanada.com/games/video-poker/ I heard a lot about online video poker and decided to try it, I hope I will be lucky and I will not be disappointed.
