  1. 1. A symbiotic relationship in which one organism benefits while the other is neither harmed nor helped.
  2. 3. The number of deaths per unit of time in a population.
  3. 4. levels The hierarchical levels in an ecosystem, consisting of producers, consumers, and decomposers, each representing a different level of energy transfer.
  4. 8. The number of individuals of a species per unit area or volume.
  5. 10. Non-living components of an ecosystem, such as temperature, sunlight, water, soil, and climate.
  6. 15. Organisms that obtain their energy and nutrients by consuming other organisms.
  7. 16. The maximum population size that an environment can sustain indefinitely given the available resources.
  8. 17. A group of organisms that are capable of interbreeding and producing fertile offspring.
  9. 20. Population growth at a constant rate of increase per unit of time, resulting in a continuously accelerating population growth curve.
  10. 21. A biological community of interacting organisms and their physical environment, including both biotic (living) and abiotic (non-living) components.
  11. 25. A symbiotic relationship in which one organism (the parasite) benefits at the expense of another organism (the host), usually by feeding on it.
  12. 26. The interaction between organisms or species for limited resources such as food, water, and territory, which can result in harm to both parties.
