Across
  1. 3. The specific environment in which an organism lives, characterized by its physical and biological features.
  2. 5. level: A hierarchical level in a food chain or food web, consisting of organisms that share the same function in the food chain and the same nutritional relationship to primary sources of energy.
  3. 7. factor: Living components of an ecosystem, including plants, animals, fungi, bacteria, and other microorganisms.
  4. 9. A large-scale ecological region characterized by distinct plant and animal communities adapted to the prevailing climate and other environmental conditions.
  5. 13. An organism, typically a plant or photosynthetic microorganism, that produces organic compounds (usually through photosynthesis) using energy from sunlight or inorganic compounds.
  6. 14. factor: Non-living components of an ecosystem, such as temperature, sunlight, soil, water, and nutrients.
  7. 16. web: A complex network of interconnected food chains that illustrates the flow of energy and nutrients through an ecosystem, involving multiple organisms at different trophic levels.
  8. 19. density: The number of individuals of a species per unit area or volume in a population.
  9. 21. A type of symbiotic relationship in which both species benefit from the interaction.
  10. 22. pyramid: A graphical representation of the trophic structure of an ecosystem, showing the flow of energy from one trophic level to another, with energy decreasing at higher trophic levels.
  11. 24. An organism that obtains energy and nutrients by consuming other organisms or organic matter.
  12. 25. The scientific study of the interactions between organisms and their environment, including both biotic (living) and abiotic (non-living) components
Down
  1. 1. A type of symbiotic relationship in which one species (the parasite) benefits at the expense of the other (the host).
  2. 2. The variety of life forms (species diversity), genetic diversity, and ecological diversity present in a given area or on Earth as a whole.
  3. 4. The total mass of living organisms in a given area or ecosystem at a specific time.
  4. 6. A close and long-term biological interaction between two different species.
  5. 8. A group of different species living and interacting with each other in a specific area or habitat.
  6. 10. curve: A graphical representation of the number of individuals surviving at each age in a population over time, often categorized into three types: Type I, Type II, and Type III, reflecting different patterns of survivorship.
  7. 11. niche: The role and position of an organism within its environment, including its habitat, its interactions with other organisms, and its utilization of resources.
  8. 12. An organism that obtains organic carbon and energy by consuming other organisms or their remains.
  9. 15. A biological community of interacting organisms and their physical environment, including both living (biotic) and non-living (abiotic) components.
  10. 17. A type of symbiotic relationship in which one species benefits while the other is neither helped nor harmed.
  11. 18. cycle: The cycling of chemical elements and compounds between living organisms, geological processes, and the atmosphere, hydrosphere, and lithosphere.
  12. 20. An organism that produces its own food (organic compounds) using energy from sunlight (photosynthesis) or from inorganic compounds (chemosynthesis).
  13. 23. An organism, usually a bacterium or fungus, that breaks down and feeds on dead organic matter, returning nutrients to the environment.
