BIO 204 Final Exam
1. What is ecology?: The study of interactions between organisms and their environment
2. What is a species?: a group of living organisms consisting of similar individuals capable of exchanging
genes or interbreeding (successfully)
3. What is a population?: a group of individuals of the same species living in the same area at the same time
4. What is a community?: All the different populations that live together in an area
5. guild community: community of species that use the same resources and same "jobs"
6. Herbivore: A consumer that eats only plants.
7. Carnivore: A consumer that eats only animals.
8. detritovores: organisms, such as dung beetles, that specialize in breaking down dead tissues and waste
products (referred to as detritus) into smaller particles
9. Decomposers: bacteria, fungi, and organisms that obtain energy from wastes or dead organisms
,10. keystone species: A species that influences the survival of many other species in an ecosystem
11. Ecosystem: A biological community of interacting organisms and their physical environment. Biotic and abiotic
components of nutrient cycles.
12. Symbiosis: A close relationship between two species that benefits at least one of the species.
13. Mutualism: A relationship between two species in which both species benefit
14. Commensalism: A relationship between two organisms in which one organism benefits and the other is
unaffected
15. mutualism example: bees and flowers
16. commensalism example: Barnacle attaches to a whale, the whale does not seem to mind.
17. Herbivore example: deer, rabbit, cow
18. Carnivore example: lion, wolves, tiger
19. Omnivore example: humans and bears
, 20. interspecific competition: competition between members of different species
21. ecological niche: the sum of a species' use of the biotic and abiotic resources in its environment
22. Predation: An interaction in which one organism kills another for food.
23. What is carrying capacity?: the number of people, other living organisms, or crops that a region can
support without environmental degradation.
24. Examples of predation and the coevolution of predators and prey.: structural and
chemical defenses, protective colors, waning coloration and mimicery
25. Parasitism: A relationship between two organisms of different species where one benefits, and the other is
harmed. Example: parasites. *Bot fly story*
