  1. 1. Non-living components that influence population size, such as temperature, light, pH, and water availability.
  2. 4. A group of organisms of the same species living in the same habitat at the same time.
  3. 5. A dynamic system comprising a community of living organisms (biotic) and the non-living (abiotic) components of their environment.
  4. 8. Living factors, including competition (interspecific/intraspecific) and predation.
  5. 10. The place where an organism normally lives, characterized by physical conditions and other types of organisms.
  6. 11. The first species to colonize bare or barren land (primary succession).
  7. 12. An organism's role within an ecosystem, including its use of resources and interactions with biotic and abiotic factors. No two species can occupy the same niche indefinitely (Competitive Exclusion Principle).
Down
  1. 2. Competition for resources between members of the same species.
  2. 3. The management of the Earth's natural resources to maintain ecosystems, often by managing succession (e.g., burning, grazing) to prevent a climax community.
  3. 6. All the populations of different species in the same area at the same time.
  4. 7. The change in an ecosystem over time, where communities of microorganisms, plants, and animals replace each other.
  5. 9. Competition for resources between members of different species.
