Across
  1. 3. Organisms which make their own energy rich molecules by using the sun’s energy to convert simple molecules into larger energy rich (organic) molecules.
  2. 6. Organism which breaks down energy rich molecules in dead organisms and the wastes of organisms into simple molecules and so help to recycle matter. Bacteria and fungi are the major decomposers.
  3. 8. The first of the hierachical groups for taxomony
  4. 9. The basic building block of living things.
  5. 10. Organism which consumes animals.
  6. 13. The state where a response is produced due to a stimulus.
  7. 14. Process of getting nutrition by organisms making their own food usually by photosynthesis
  8. 16. To increase the apparent size of an object.
  9. 17. Organism which consumes other organisms (prey) that they actively hunt.
  10. 19. A membrane-bound fluid filled space within a cell that is used to store, water, waste and food molecules.
  11. 22. The state where an organism has a definite structure and is made up of cells. (two words)
  12. 25. One of the five kingdoms of living things
  13. 26. A number of food chains combined. (two words)
  14. 27. An organism composed of many cells.
  15. 29. Organism which consumes both plants and animals.
  16. 31. Process by which green plants manufacture their own energy rich food molecules.
  17. 32. One of the five kingdoms of living things
  18. 33. A change in an organism’s environment which produces a response.
Down
  1. 1. Areas on the Earth with similar climatic conditions.
  2. 2. An organism whose cells have membrane-bound organelles including a proper nucleus.
  3. 4. An organism made up of one cell.
  4. 5. The variety of all living things; the different plants, animals and microorganisms, the genetic information they contain and the ecosystems they form.
  5. 6. The process by which fertile land becomes desert, typically as a result of drought, deforestation, or inappropriate agriculture.
  6. 7. The last of the hierachical groups for taxomony
  7. 11. The simultaneous demand by two or more organisms for limited environmental resources, such as nutrients, living space, or light.
  8. 12. The study of the interactions between living things and their environment.
  9. 15. The place on the earth’s surface where all life dwells. Within the biosphere there are many different biomes which in turn contain many different ecosystems.
  10. 18. The process whereby food is broken down to release energy.
  11. 20. Two word (binomial) system used to name organisms using the genus and species names for the organism.
  12. 21. Organism which eats other organisms to obtain the energy rich organic molecules and nutrients it needs.
  13. 23. The practice of classifying organisms.
  14. 24. The control center of the cell, where DNA is found.
  15. 28. An instrument with lenses which magnifies objects.
  16. 30. Feeding level within the community. (two words)
  17. 31. Organism which is actively hunted by predators.
