Across
- 4. The study of relationships between two organisms and between an organism and its environment
- 6. The variety of organisms considered at all levels, from populations to ecosystem
- 7. Greater impact on a more dense population
- 14. Aspects of the environment that limit the size a population can reach
- 21. Community plus all of the abiotic factors in the environment

Down
- 1. Impact is independent of population density, therefore the same impact on more dense and less dense populations
- 2. Multiple ecosystems that share similar characteristics but are located in different parts of the planet
- 3. An underground layer of permeable rock that can hold water
- 5. The theoretical maximum population that a given environment could support
- 8. Multiple organisms of the same species living together
- 9. A graphic representation of mortality patterns, showing the number of individuals in a population that can be expected to survive to any specific age
- 10. All of the chemical reactions of each cell in an organism that provide energy for life’s processes and create key molecules
- 11. A population that grows without limit
- 12. A population that grows quickly at first but levels off at the carrying capacity due to limited resources
- 13. Individual member of a species or population
- 15. Multiple populations of different species living together
- 16. The zone of life on Earth, encompassing all of Earth’s ecosystems
- 17. Diagram that shows relatedness of organisms
- 18. Living
- 19. A group of organisms of the same species living in the same place
- 20. Nonliving
- 23. Field of biology that classifies organisms, organizing them based on similar characteristics
