Ecosystems
Unit #10
1.
ecology: study of the interactions
of organisms with one another and their environment
2.
abiotic: describes nonliving parts
of environment, such as water, rocks, and light
3. biotic: describes living factors in the environment
4. population: group of organisms of the same species that live in a specific
area
5. community: all the populations of species that live in the same habitat and
interact with each other
6. ecosystem: community of organisms and their abiotic environment
7. biosphere: part of Earth where life exists
8. herbivore: organism that eats only plants
9. carnivore: organism that eats
animals (meat)
10. omnivore: organism that eats both plants and animals
11. food chain: diagram that shows how energy in food flows from one organism to
another
12. food web: diagram that shows the
feeding relationships between organisms in an ecosystem
13. energy pyramid: triangular diagram that
shows ecosystem’s loss of energy
14. carrying
capacity: largest population that an
environment can support at any given time
15. prey: organism that is killed and eaten by another organism
16. predator: organism that eats all or parts of another organism
17. symbiosis: close long-term
association between two or more species
18. mutualism: symbiotic relationship in which both organisms benefit
19. commensalism: symbiotic relationship in which one organism benefits and one is
unaffected
20. parasitism: symbiotic relationship in which one organism benefits (parasite)
and one is harmed (host)
21. coevolution: evolution of two species
because of their close interactions with one another
22. evaporation: change of substance from liquid to gas
23. condensation: change of substance from
gas to liquid
24. precipitation: any form of water that falls to the Earth’s surface from the clouds
25. decomposition: breakdown of substances
into simpler molecular substances
26. combustion: burning of a substance
27. succession: replacement of one type
of community with another in a single place over time
28. pioneer species: first organisms to live in an area
