Honors Bio II Part 2
| Question | Answer |
|---|---|
| Effect of Evolution | causes natural selection to favor counter adaptations |
| Coevolution | as preys defense evolves so does predators offense |
| Nutrient exclusion | Deposits of silica, tough to eat Did not store any nutrients, ate it all |
| secondary chemical compounds | plants(and algae) contain diverse secondary compounds that are toxic to most herbivores or greatly disturb their metabolism |
| Allelopathy | Production of toxic substances that inhibit the growth of nearby plants...decreases competition |
| Responses of herbivores to plant defenses | ceratin groups of herbivores associated with each family or group protected by particular kind of secondary compound... eliminated competition |
| poisons | injested or applied, produce toxic alkaloids in mucus that covers brightly colored skin |
| Venom | injected or stinging |
| neurotoxins | attack the brain, paralyze nerve centers that control respiration and heart action |
| hemotoxins | attack the blood stream, damage blood vessels and cause hemmorage |
| aposomatic coloration | warning colors, bright colors to advertise poisonous nature |
| cryptic coloration | blending in with environments, blends surroundings and hides individual from predators |
| Disruptive colorations | breaks up body outline so individual cant be singled out by predator...ex: zebra, butterfly fish, moths |
| counter-shading | light on underside to blend in with sun, dark on backside to blend in with ocean floor or ground |
| Batesian mimicry | mimic resembles model(aposomatic colored), mimics avoided by predators who were fooled |
| Mullarian | unrelated but protected animal species come to resemble one another |
| symbiosis | all relationships carry potential for coevolution |
| Parasitism | symbiotic relationship in which one species benefits but other is harmed |
| Ectoparasites | Parasites that feed on exterior surface of an organism |
| Parasitoids | Insects that lay eggs on a living host |
| Endoparasites | parasites that live within body of hosts, ex: tapeworm |
| manipulative parasites | makes host do something weird, may involve life cycle that involves 2 or more hosts |
| Commensalism | symbiotic relationship in which one species benefits while other neither benefits nor is harmed |
| mutualism | symbiotic relationship in which both participating species benefit |
| Succession occurs? | because species alter habitat and resources available in ways that favor other species |
| Primary succession | occurs on bar; lifeless substrate |
| pioneer species | are the first to appear; highly dispersal rates (r-strategists), species turnover, create an environment for new species |
| As succession occurs | leads to increase in biomass, diversity, size of organisms, lifespans, and stability |
| climax community | last group of organisms that make up a community |
| secondary succession | begins with a disturbance, but soil is till there, faster succesion |
| Alien species | species not native to an area, may out compete native species |
