living world - Coggle Diagram

- - - - the angular distance of a place north or south of the earth's equator, or of the equator of a celestial object, usually expressed in degrees and minutes.
      - In the lower latitudes, such as the tropics, temperatures are the highest. This is because the sun's rays travel a shorter distance to the Equator and are therefore more concentrated.
      - higher latitudes, such as the polar regions of the world, temperatures are lowest. This is due to the sun's rays travelling a longer distance
  - - - Low-pressure areas are associated with cloud and precipitation (rainfall)
        
        as the air rises it cools, condenses and forms clouds
        
        the water droplets in the clouds increase in size
        
        they eventually become too heavy to be held and fall as precipitation
    - - High-pressure areas are associated with dry, warm and settled weather conditions. This is because sinking air does not result in precipitation
- - - - the temperature and amount of rainfall, determine which species can survive in that ecosystem
    - - the type is very important. it provides nutrients that support different plants
    - - the avability of water ca determine which plants and animals can live in that ecosystem
  - - - at the bottom of the pond there is a very little amount of oxygen or light. decomposers and scavengers live at the bottom where they feed on dead materials like water worms and rat-tailed maggots.
    - - at the mid point of the pond the main predators are fish. food is found in all the sections of the pond. the bottom , middle and the surface.
    - - animals at this level breath through there gill, skin or lungs. there is a lot of oxygen and light on the surface. animals here are ducks, water boatmen, midge larvae and tadpoles
    - - birds such as kingfishers and insects like dragonflies
    - - a food chain shows how each living thing gets food. and how energy and nutrients are passed from organism to another.
        
        the producer gives the basic source of energy and nutrients. then the consumers feeds on the energy and nutrients and it carries on till the predator the top of the food chain
    - - this includes all of the connections between producers and consumers in an ecosystem. the food web shows how interconnected all of the different organisms
  - - - natural factors
        
        drought
        
        flood
        
        fire
        
        disease
      - human factors
        
        introducing more animals
        
        altering the drainage of the land which may influence the amount of water
        
        changing the pH level of the water
        
        altering the nutrients levels of the water if fertilisers are leached into the water resulting in eutrophication
