- 7. the short term state of the atmosphere at a specific time and place, including the temperature, humidity, cloud cover, precipitation, wind, etc.
- 9. occurs in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from a retreated glacier, is deposited
- 10. a kind of animal that eats either other animals or plants
- 12. the branch of biology that deals with the relations of organisms to one another and to their physical surroundings

- 17. place where an organism or a community of organisms lives, including all living and nonliving factors or conditions of the surrounding environment
- 18. distance north or south of the equator, measured on a meridian
- 21. the functional role an organism plays in an ecosystem, determined by the abiotic factors, which comprise of living features such as animals, plants and fungi, and biotic factors
- 22. a form of symbiosis in which one organism benefits at the expense of another organism usually of different species
- 24. a relationship between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter

- 1. an organism that serves as a primary producer in a food chain, they obtain energy and nutrients by harnessing sunlight through photosynthesis or obtain chemical energy through oxidation to make organic substances from inorganic ones
- 2. an animal that eats a diet consisting mainly of meat, whether it comes from live animals or dead ones
- 3. an organism that cannot manufacture its own food by carbon fixation and therefore derives its intake of nutrition from other sources of organic carbon, mainly plant or animal matter
- 4. the long term patterns of temperature, humidity, wind, etc. in an area
- 5. an organism that feeds on and breaks down dead plant or animal matter, returning essential nutrients to the ecosystem
