Bio EOCT Domain IV
Review of EOCT content for ecology
| Question | Answer |
|---|---|
| study of the interactions between living things and the environment | ecology |
| all organisms and the environments in which they live; all places on earth that supports life | biosphere |
| all the living things in an environment | biotic factors |
| all the nonliving things in an environment | abiotic factors |
| organisms of the same species in a given area | population |
| a collection of populations that interact with each other in a given area | community |
| all the biotic and abiotic factors in a given area | ecosystem |
| a collection of ecosystems sharing similar vegetation and climate | biome |
| number of organisms of the same species living in a given area | population density |
| population growth under ideal conditions | exponential |
| J-shaped curve of population growth | exponential |
| population growth when there are limiting factors | logistic |
| S-shaped curve of population growth | logistic |
| maximum size of a population that an environment can support | carrying capacity |
| when the death rate is equal to the birth rate | zero population growth |
| type of limiting factor based on the size of the population Examples- competition, overcrowding, food and water resources | density-dependent |
| type of limiting factor where the size of the population has no effect Examples- flooding or fire | density-independent |
| the role or job an organism has in the environment | niche |
| place where an organism lives | habitat |
| ecosystems on land | terrestrial |
| ecosystems in the water | aquatic |
| biome with permafrost, very cold, basically treeless, arctic fox and snowy owl | tundra |
| biome with large coniferous trees, acidic soil, black bear and wolves | taiga |
| biome with frequent rain, found near equator,temperature near 80 F toucans, monkeys, parrots | tropical rain forest |
| biome can be hot or cool, very little rainfall, camels,jackrabbit, many reptiles, cacti | desert |
| biome with uneven rainfall, many grasses and small plants, many grazing herbivores: bison, antelope | grasslands |
| biome with 4 seasons, rabbits, squirrels, birds, trees lose leaves in winter | temperate deciduous forest |
| ultimate source of energy in an ecosystem | sun |
| organisms in an ecosystem that harness the sun's energy to make food molecules | producers or autotrophs |
| organisms in an ecosystem that eat other organisms to obtain energy | consumers or heterotrophs |
| organisms that feed on dead organisms | decomposers |
| shows how energy flows in an ecosystem | food chain |
| a step or feeding level on a food chain | trophic level |
| all the possible feeding relationships in an ecosystem | food web |
| feeds on producers in a food chain | primary consumer |
| feeds on herbivores | secondary consumer |
| amount of energy passed on to each trophic level | 10% |
| energy ____________ through an ecosystem | flows |
| matter ____________ through an ecosystem | recycles |
| form carbon is found in the atmosphere | carbon dioxide |
| percentage of nitrogen in the atmosphere | 78% |
| bacteria do this to make nitrogen accessible for plants to make proteins | nitrogen fixation |
| How is carbon dioxide in the atmosphere used by plants to make sugars? | photosynthesis |
| How is carbon returned to the atmosphere in the carbon cycle? | respiration, decomposition, burning fossil fuels |
| the natural changes that take place in an ecosystem over time | succession |
| the gradual changes in an ecosystem where no life has existed before; from bare rock | primary succession |
| type of succession after a volcano | primary succession |
| organisms that first inhabit an area | pioneer organisms |
| examples of pioneer organisms | mosses and lichen |
| changes after a natural disaster or human activity partially destroys an environment | secondary succession |
| type of resource that is replaced by natural processes | renewable |
| type of resource that is only present in limited amounts | nonrenewable |
| the contamination of air, soil, or water from human activity | pollution |
| primary cause of air pollution | burning of fossil fuels to produce electricity |
| solids in the air that can have a negative effect on living things; soot | particulates |
| a combination of smoke, gases, and fog | smog |
| sulfur oxides in the atmosphere that mix with water vapor in the clouds which damages crops and harms living things in aquatic environments | acid rain |
| carbon dioxide traps heat from the sun warming the Earth | greenhouse effect |
| excess heat from the greenhouse effect causing temperatures to rise on the earth | global warming |
| ozone layer that prevents harmful UV rays from sun reaching the earth is broken down by these | CFC's Cholofluorcarbons |
| response of a plant seedling to gravity | geotropism |
| response of a plant seedling to water | hydrotropism |
| response of a plant seedling to light | phototropism |
| response of a plant seedling to touch | thigmotropism |
| This is when a toxin is added to the environment and it increases in concentration in each organism as it moves up the food chain | biomagnification |
