- 1. an organism that can produce its own food from natural sources like sunlight or inorganic chemicals
- 5. the part of its fundamental niche that a species occupies
- 9. any individual living thing, encompassing a wide range of life forms from single-celled bacteria to complex multicellular animal
- 12. energy from organic waste and dead bodies, release nutrients back into environment (decomposers: worms, bacteria, fungi)
- 13. succession that occurs in areas where there has been previous growth (ex: forest fires, forest clearings)
- 14. an organism that cannot produce its own food and instead obtains energy by consuming other organisms
- 17. a specific level in an ecosystem based on the organism’s source of energy
- 19. the entire range of conditions an organism is potentially able to occupy
- 20. major biological community that occurs over a large area of land
- 22. one organism feeds on and usually lives on or in another, does not usually kill the host (ticks)

- 7. a close and prolonged interaction or relationship between two or more different biological species
- 8. the physical, or non-living aspects of a habitat.
- 10. - regular progression of species replacement.
- 11. illustrates the flow of energy and nutrients as one organism consumes another
- 15. Study of interactions of living organisms with one another and with their physical environment
- 16. an organism, often bacteria or fungi, that breaks down dead organic matter
- 18. the natural environment where an organism lives
- 21. succession that occurs where plants have not grown before (ex:volcanoes, receding glaciers).
