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.
