Down
  1. 1. organism which ingests non-living organic matter
  2. 2. comes from living or once living things (contains carbon and hydrogen)
  3. 3. graphical way to show change in biomass and energy through trophic levels
  4. 7. organism which takes organic nutrients from other organisms
  5. 9. shows ALL the food chains in an ecosystem
  6. 11. does not come from living or once living things (e.g. water, gases in air, simple minerals)
