study of all the interactions organisms and their environment

any nonliving part of the environment, such as water, sunlight, temperature, and air

any living or once-living organism in the environment

all of the individuals of one species that live in the same space at the same time

all of the population of different species in a given area that interact in some way and depend on one another for food, shelter, and other needs

all of the communites in a given area and the abiotic factors that affect them

part of the Earth that supports life, the top part of Earth's crust, all the waters covering Earth's surface, and the surrounding atmosphere, includes all biomes, ecosystems, communites, and populations

number of individuals in a population that occupies an area of limited size

any biotic or abiotic factor that limits the munber of individuals in a population

any close interaction among two or more different species, including mulualism, commensalism, and parasitism

role of an organism in the ecosystem, including what it eats, how it gets its food

model that describes how energy passes from one organism to another

model that describes how energy from food moves through a community, a series of overlapping food chains

continuous cycle of water molecules on the Earth as they rise into the atmosphere, fall back to the Earth as rain or other precipitation, and flow into rivers and oceans through the processes of evaporation, condensation, and precipitation
