Across
  1. 2. / a system of interlocking and interdependent food chains
  2. 4. / when energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on
  3. 7. / a hierarchical series of organisms each dependent on the next as a source of food.
  4. 9. / the process of change in the species structure of an ecological community over time. The time scale can be decades, or even millions of years after a mass extinction.
  5. 10. / Relating to or resulting to living things; especially in their ecological relations
  6. 11. / the series of processes by which carbon compounds are interconverted in the environment
  7. 14. / relationship between two organisms where one benefits, and the other is harmed
  8. 17. / all the different species living in the same place
  9. 18. / The action or process of adapting or being adapted
  10. 19. / the point where new species come into the community at the same time as others leave making it a stable, mature community with little change in the number of species
  11. 20. / a relation between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter
  12. 22. Species / The first organisms to grow back after ecological succession occurs
Down
  1. 1. / hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy.
  2. 3. / the establishment of a community in an area of bare rock that does not have topsoil
  3. 5. / A pyramid that shows the flow of energy or biomass at each trophic level in a particular ecosystem as well as the feeding relationships of groups and organisms
  4. 6. / when a disturbance such as a fire or flood destroy a community
  5. 8. / the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms
  6. 12. / all organisms of the same species living in the same place at the same time
  7. 13. / living and nonliving things in the same place
  8. 15. / interaction where a predator kills and eats its prey
  9. 16. / a relationship beneficial to both organisms involved
  10. 21. / Physical rather than biological; not derived from living organisms
