Adaptions + Survival
Unit 2 Biology: Chapter 10
| Question | Answer |
|---|---|
| Keystone Species | An organism that has a disproportionately large positive effect on an ecosystem. (E.g. Bee, Shark) |
| Indicator Species | A species whose presence indicates a particular state of ecosystem health. (E.g. Algae) |
| Parasitism | Uses host for resources but does not kill it. (+/-) |
| Mutualism | Both species benefit. (+/+) |
| Commensalism | One benefits, one is not affected. (+/0) |
| Amensalism | One is harmed, other is not affected. (-/0) - E.G. Cattle stomping on Plants |
| Predation | One species kills and eats another. (+/-) |
| Micropredation | Eats but does not kill. (+/-) |
| Interspecific Competition | Two species compete for the same resource. (-/-) |
| Symbiosis | Ecological relationship in which two species live together in close association. |
| Ecological Relationship | Any interaction between two species in an ecosystem |
| 5 Adaptions to Arid Environments | SA:V larger, Enable water storage (plants), Body temp allowed to rise, Overall conserve water, Small size, etc. |
| 5 Adaptions to Cold Environments | SA:V smaller, Large Size, Thick Insulating layer, low growing form (plants), Endotherms |
| Endotherm | Internal, body temperature stays the same. |
| Ectotherm | External, body temperature depends on environment. |
| Structural Adaptations (meaning) | Physical. (Giraffe's long neck, etc.) |
| Behavioral Adaptations (meaning) | Way it acts. (Bird calls, etc.) |
| Physiological Adaptations (meaning) | Processes. (Release of toxins, etc.) |
