water and carbon cycle

Cards (22)

  • environmental changes affect the distrubution of organisms
  • Give three environmental factors that can affect organism distribution
    availability of water
    temperature
    atmospheric gases
  • The water cycle means water is endlessly recylced
  • Energy from the sun makes water evaporate from land and sea, turning it into water vapour
  • warm water vapour is carried upwards and when it gets higher it cools and condenses to form clouds
  • water falls from clouds as precipitation onto land where it provides fresh water for plants and animals
  • Water evaporating from plants is called transpiration
  • elements are cycled back to the start of the food chain by decay
  • living things are made up of materials they take from around them. name the ones plants take and use
    carbon
    oxygen
    hydrogen
    nitrogen
  • What do plants convert the materials they take from around them into?
    complex compounds
  • materials used up in the food chain are eventually returned to the environment as waste products when..
    organisms DIEEEEE and DECAYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
  • MATERIALS DECAY BECAUSE THEY ARE BROKEN DOWN BY MICROORGANISMS
  • decay happens in moist, oxygen rich conditions which are warm
  • decay puts mineral ions back into the soil
  • The constant cycling of carbon is called the carbon cycle
  • co2 is removed from the atmosphere by green plants during photosynthesis
  • When plants and algae are eaten by animals carbon becomes apart of the fats and proteins in the animal and moves up the food chain
  • When animals respire carbon is returned to the atmosphere in the form of carbon dioxide
  • when animals and plants die, detritus feeders and microorganisms feed on their remains
  • when microorganisms respire, co2 is returned to the atmosphere
  • animals produce waste that is broken down by detritus feeders and microorganisms
  • the combustion of wood and fossil fuels returns carbon into the atmosphere
