Ecology
| Question | Answer |
|---|---|
| relationship where both benefit | mutualism |
| relationship where 1 benefits, other is harmed | parasitism |
| relationship where 1 benefits, other is not helped or harmed | commensalism |
| relationship where 1 benefits, other is killed | predation |
| members of the same species in the same area | population |
| living factors in ecosystem | biotic |
| non-living factors in ecosystem | abiotic |
| 2 or more populations in the same area | community |
| all of the populations and non-living environment | ecosystem |
| organism that eats meat and plants | omnivore |
| organism that makes its own food | producer/autotroph |
| organism that must eats its food | consumer/heterotroph |
| organism that eats only meats | carnivore |
| organism that eats only plants | herbivore |
| size of population matters (spread of disease, competition) | density-dependent limiting factor |
| size of population does NOT matter (disasters, human activity) | density-independent limiting factor |
| species important for stability of the ecosystem | keystone species |
| says that competition leads to "losing" species either moving to different niche or extinction | competitive exclusion principle |
| where an organism lives | habitat |
| what an organism does to survive where it lives | niche |
| succession where there is no soil & needs pioneering species | primary succession |
| succession where there is soil & surviving species | secondary succession |
| organism that breaks down dead materials to recycle nutrients | decomposer |
| carpooling, less factories, electric cars, reforesting | positive human activity |
| more factories, more buildings, clearing forests, overhunting | negative human activity |
| negative impact of too much Carbon Dioxide in atmosphere | Greenhouse Effect and Global Warming |
| This cycle is depends on the weathering of rocks | Phosphorus cycle |
| this cycle uses bacteria, lightning strikes and fires for making amino acids % fertilizer | Nitrogen Cycle |
| this cycle involves precipitation, transpiration and evaporation | Water Cycle |
| this cycle involves fossil fuels and carbon dioxide | Carbon Cycle |
| species that is new to area that uses up resources because it has no native predators | invasive species |
| species that can tell the overall health of its ecosystem | indicator species |
| this much energy makes it to the next trophic level | 10% |
| pollution and toxins increase as you move up the energy pyramid | biomagnification |
| things that increase a population's size | births and immigration |
| things that decrease a population's size | deaths and emigration |
| population distribution close together ; safety in numbers | clumped |
| population growth that starts fast, slows down and stops (S-shaped curve) | logistic growth |
| population growth that starts fast and is constant (J-shaped curve) | exponential growth |
| something that causes succession | disturbance |
| sunlight + carbon dioxide + water --> glucose + oxygen | photosynthesis |
| glucose + oxygen --> carbon dioxide + water + ATP energy | cellular respiration |
| Cycle that happens in Cellular Respiration | Krebs Cycle |
| Cycle that happens in Photosynthesis | Calvin Cycle |
| where photosynthesis happens (organelle) | chloroplast of plant cells |
| where cellular respiration happens (organelle) | mitochondria of plant and animal cells |
| process that makes only 2 ATP when oxygen is not available | fermentation |
| the largest population size the ecosystem can support (max #) | carrying capacity |
| chemical energy that is made during cellular respiration | ATP |
