autotrophs

consumers
organisms that rely on other organisms for energy and nutrients
food chain
a series of organisms in which energy is transferred from one organism to another
food web
a network of feeding interactions, through which both energy and matter move
ecological pyramids
models that show the relative amount of energy or matter contained within each trophic level in the food chain or food web
pyramids of energy
they show the relative amount of energy available at each trophic level of a food chain or food web
biomass
the total amount of living tissue within a trophic level
pyramid of biomass
a model that illustrates the relative amount of living organic matter in each trophic level of an eco system
pyramid of numbers
a model that shows the relative number of individual organisms at each trophic in an eco system
nutrients
the elements that each organism needs to sustain its life
Mill’s Water Wheel
biogeochemical cycles are powered by the one way flow of energy via the biosphere
water cycle
water continuously moves between Earth’s surface and the atmosphere. This movement occurs by different physical processes
