Question | Answer |
Climate | the average weather of an area. Tropical/Temperate/Polar. Temperature and Precipitation are the biggest factors. |
Weather | the immediate are actual atmospheric conditions at the moment. It is hot, rainy, storm, windy etc. |
Latitude | A primary predictor of climate, the measure of how far a place is from the equator |
Polar | colder climate area with two distinct season winter/summer |
Temperate | climates that experience four equal seasons |
Tropical | areas that are warm all year usually a wet and dry seasons. |
Microclimate | areas within a climate that has a slightly different climate due to localized landforms. |
Greenhouse effect | The effect of increasing temperature due to the trapping of heat energy by greenhouse gasses. CO2, H20 and methane are the gases that cause |
Earth’s axis | causes the different climates and seasons |
Tolerance | the ability of an organism to survive adverse conditions |
Habitat | the physical place in which an organism lives |
Niche | the unique role an species has on the environment |
Resource | something an organism uses for survival |
Intraspective/intrespective competition | competition between the same species/competition between different species for a resource |
Competitive exclusion principle | means no two organisms can occupy the same niche. One species will always outcompete the other to extinction. |
Predation | the act of hunting and killing for food |
Herbivory | the act of eating plants for food |
Keystone species | a species that is so integral to the food web that changes to the population of the keystone species has a significant effect on the other species. |
Symbiosis | a relationship between two organisms that has a long lasting and significant effect on one or both species |
Mutualism | type of symbiosis in which both organisms benefit |
Parasitism | type of symbiosis in which one organism is harmed |
Commensalism | type of symbiosis in which one organism benefits and the other is unaffected. |
Ecological succession | is the evolution of an ecosystem from no living species to living species or from one set of species to a different set of species over time |
pioneer species | are the first type of organisms to inhabit a habitat. Ex. Algae, bacteria, lichen |
primary succession | the first time a group of species inhabit a location. |
climax community | the types of organisms that are the final types of organisms that will inhabit a habitat. Ex Oak Forests, Old Growth Forests. |
natural vs. man made disturbances | forest fires by lightning, a farm field being made |
biological equilibrium(not in book) | when a regular patter of succession or populations is developed. Ex. Populations of predators and prey natural go up and down, or tree falls in forest and new species move in until it is filled again. |
Chapter 4.4 | look in book or ppt for different biomes, know how to read the graphs. |
