Ecology
ecolgical disruptions
| Question | Answer |
|---|---|
| ecosystem | all organisms interacting with their environment |
| abiotic | nonliving parts of an ecosystem |
| biotic | living parts of an ecosystem |
| producers | make their own food and give off oxygen |
| consumers | eat plants and other animals and give off carbon dioxide |
| decomposers | turn dead animals and plants into nutrients for other organisms to grow |
| niche | the role a species has in its environment |
| biodiversity | variety of life on earth, filling niches |
| some important functions of ecosystems | purify the air, provide food, maintain soil, recycle nutrients |
| anthropogenic | human-made |
| possible causes of seasonal changes in ecosystems | heavy rain, flooding, blizzard |
| short-term ecological disruptions | happen quickly leaving no time for organisms to change or adapt |
| long-term ecological disruptions | happen slowly allowing organisms to adapt to survive, ecosystem permanently changed |
| eutrophication | nutrient pollution leads to depleted oxygen in an aquatic ecosystem |
| dead zone | area of an aquatic ecosystem where hypoxia exists and organisms can't survive |
| acidification | pH of the water is decreased primarily due to increased carbon dioxide concentration |
| steps in eutrophication process | nutrient pollution, overgrowth of algae (algae blooms), depletion of oxygen due to decomposition, dead zone in which organisms can't survive |
| weather | short-term changes in the atmosphere |
| climate | average weather of a location over time |
| signs of climate change | global warming, rising sea level, more droughts, warmer oceans, wilder weather |
| natural causes of climate change | ocean currents, volcanic eruptions, sun energy, changes in earth's orbits |
| various environmental factors affected by climate change | plant growth stages, migration patterns, water quality |
| adaptive evolution | happens more quickly when species are under especially strong selective conditions |
| nonheritable | can't be passed from parent to offspring |
| secondary succession | ecological process that occurs after a natural disaster or human activity where soil is present |
| primary succession | ecological process that occurs when no soil is present |
