  1. 3. Organisms, such as fungi and bacteria, that break down dead or decaying organisms, recycling nutrients back into the ecosystem.
  2. 5. Web A complex network of interconnected food chains within an ecosystem, showing the multiple feeding relationships among organisms.
  3. 7. Chain A linear sequence of organisms where each is eaten by the next higher trophic level, showing the flow of energy.
  4. 10. Organisms that cannot produce their own food and must consume other organisms for energy (e.g., animals, fungi).
  5. 13. An organism that feeds on other organisms for energy; can be classified as primary, secondary, or tertiary based on its position in the food chain.
  6. 15. Organisms that produce their own food from inorganic substances, typically through photosynthesis or chemosynthesis (e.g., plants, algae).
  7. 18. A community of organisms interacting with their physical environment (abiotic factors) as a system.
  8. 20. The process by which some organisms (like certain bacteria) use chemical energy from inorganic compounds to produce food, often in the absence of sunlight.
  9. 22. Level The position an organism occupies in the food chain or food web, typically categorized as producers, primary consumers, secondary consumers, etc.
  10. 23. An organism that feeds exclusively on plants or plant-based material.

  1. 1. An organism that feeds exclusively on other animals.
  2. 2. Pyramid A graphical representation showing the relative amounts of energy, biomass, or numbers of organisms at each trophic level in an ecosystem.
  3. 4. The study of interactions between organisms and their environment, including both biotic (living) and abiotic (non-living) components.
  4. 6. An organism (usually a plant or algae) that produces its own food and forms the base of the food chain by converting sunlight or chemicals into energy.
  5. 8. Organisms that feed on dead organic material (detritus), such as decomposing plants or animals.
  6. 9. The process by which plants, algae, and some bacteria convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.
  7. 11. An organism that feeds on both plant and animal matte
  8. 12. The total mass of living organisms in a given area or ecosystem at a specific time.
  9. 14. A group of individuals of the same species living in the same area at the same time.
  10. 16. The global sum of all ecosystems; the zone of life on Earth, including land, water, and atmosphere.
  11. 17. All the different species living and interacting in a particular area.
  12. 19. A group of organisms that can interbreed and produce fertile offspring under natural conditions.
  13. 21. A large geographical area characterized by distinct climate, flora, and fauna, typically categorized by temperature and precipitation patterns (e.g., desert, forest).
