  1. 1. Cycle, the process through which carbon is exchanged between the atmosphere, living organisms, and the Earth – helps regulate carbon levels on Earth.
  2. 5. the place or environment where an organism lives – it provides everything the organism needs to survive, such as food, water, shelter, and space.
  3. 6. refers to anything that has mass and takes up space – makes up all living and nonliving things
  4. 7. a close relationship between two different species living together – this relationship can be beneficial, neutral, or harmful to one or both of the organisms involved. (there are three main types: commensalism, mutualism, and parasitism)
  5. 8. the process by which certain organisms produce their own food using energy derived from chemical reactions, rather than from sunlight – typically occurs in environments where sunlight is unavailable
  6. 9. refers to the role or function of an organism within its environment, including how it gets its food, where it lives, and how it interacts with other organisms
  7. 10. organisms that cannot produce their own food and must obtain energy by consuming other organisms, such as plants, animals, or both – called "consumers" because they rely on other living things for nutrition
  8. 12. Species, an organism that has a large impact on its ecosystem – its presence and activities help maintain the structure and diversity of the ecosystem.
  9. 15. the ability of an ecosystem or organism to recover or bounce back from disturbances or changes, such as natural disasters or environmental stress
  10. 18. different parts of an ecosystem or living organisms are linked or depend on each other in some way
  11. 19. the ability of an organism to survive and function within a range of environmental conditions, such as temperature, humidity and availability of resources
  12. 20. Cycle, the process by which nitrogen moves between the atmosphere, soil, and living organisms
Down
  1. 2. organisms that produce their own food using light – called "producers" because they create the energy-rich compounds that other organisms rely on for food
  2. 3. a community of living organisms interacting with each other and their physical environment
  3. 4. refers to the total amount of living or recently living organic matter in an ecosystem – often used as a measure of energy or mass available in an ecosystem at different trophic levels
  4. 5. Restoration, the process of helping to repair or improve a damaged or degraded habitat to bring it back to a healthier, more natural state – involves actions like planting native plants or cleaning up pollution
  5. 11. Levels, a position or step in the food chain or food web, based on how an organism obtains its energy
  6. 13. a large geographical area characterized by its specific climate, plants, and animals – it includes ecosystems with similar environmental conditions, such as deserts, forests, grasslands, and tundras.
  7. 14. Fragmentation, the process where large, continuous habitats are broken into smaller, isolated pieces, often due to human activities like construction or deforestation – can make it harder for species to find food, mates, or migrate
  8. 16. refers to the variety of different living organisms in an area, including plants, animals, fungi, and microorganisms
  9. 17. when two or more organisms fight for the same limited resources, such as food, water, or space, in their environment
