- 1. Cycle, the process through which carbon is exchanged between the atmosphere, living organisms, and the Earth – helps regulate carbon levels on Earth.
- 5. the place or environment where an organism lives – it provides everything the organism needs to survive, such as food, water, shelter, and space.
- 6. refers to anything that has mass and takes up space – makes up all living and nonliving things
- 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)
- 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
- 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
- 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
- 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.
- 15. the ability of an ecosystem or organism to recover or bounce back from disturbances or changes, such as natural disasters or environmental stress
- 18. different parts of an ecosystem or living organisms are linked or depend on each other in some way
- 19. the ability of an organism to survive and function within a range of environmental conditions, such as temperature, humidity and availability of resources
- 20. Cycle, the process by which nitrogen moves between the atmosphere, soil, and living organisms
Down
- 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
- 3. a community of living organisms interacting with each other and their physical environment
- 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
- 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
- 11. Levels, a position or step in the food chain or food web, based on how an organism obtains its energy
- 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.
- 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
- 16. refers to the variety of different living organisms in an area, including plants, animals, fungi, and microorganisms
- 17. when two or more organisms fight for the same limited resources, such as food, water, or space, in their environment
