Term | Definition |
Ecology | The study of the interactions that take place among organisms and their environment |
Population | All the organisms in an ecosystem that belong to the same species |
Community | All the populations in an ecosystem |
Habitat | provides shelter and resources so that animals can survive |
Niche | the role of an organism in its ecosystem |
Producer | makes its own energy through photosynthesis (aka autotroph) |
Consumer | must consume other organisms to gain energy (aka heterotroph) |
Biotic | living |
Abiotic | nonliving |
Limiting Factor | any resource that limits how large a population can grow |
Competition | Organisms attempt to use an ecological resource at the same place and the same time |
Resource | anything necessary to survive (food, water, space, mate, shelter, oxygen, sunlight) |
Predation | Interaction where a consumer captures and feeds on another consumer |
Predator | Organism that does the killing and eating |
Prey | Organism that is being killed and eaten (victim) |
Symbiosis | Any close relationship between two species |
Mutualism | Both species benefit from the relationship (+/+) |
Commensalism | One member of the relationship benefits while the other is neither harmed nor helped. One |
Parasitism | One organism lives on or inside another organism and harms it (+/ |
Host | Organism that is harmed in a parasitic relationship; the one that provides the nutrients to the parasite |
Parasite | Organism that gets its nutrients from the host |
5 Basic Needs | Oxygen, Food, Water, Living Space, Proper Temperature |
Adapting | to change in order to make “fit” or suitable for an environment |
Adaptation | any body structure or behavior that helps an organism survive |
Structural Adaptation | physical characteristics that help an organism survive |
Behavioral Adaptation | Activities performed by an organism to help it survive |
Camouflage | an adaptation where an animal can hide by blending in with its surroundings |
Mimicry | an adaptation where one organism imitates another organism |
Instinct | a pattern of behavior that requires no thinking |
Migration | an instinctive behavior in which some animals move from one place to another for a period of time |
Hibernation | an instinctive behavior in which some animals spend the winter in an inactive condition |
Learned Behavior | a behavior that an animal learns through experience |
Natural Selection | over time, populations change naturally. Beneficial traits become more common. Harmful traits become less common (and eventually disappear) |
Selective Breeding | Humans select specific organisms to breed together, in order to get certain “desirable” traits |
