definition of pyramid of numbers
a model used by ecologists to show how many organisims are at each level in a good chain, producers at the bottom of the pyramid and fewer organisims at the top
a model used by ecologists to show how many organisims are at each level in a good chain, producers at the bottom of the pyramid and fewer organisims at the top
definition of pyramid of numbers

definition of photosynthesis
when producers trap energy from the sun to make food

water cycle
the continuous movement of water through the environment; the water cycle consists of evaporation, transpiration, condensation, and precipitation
the continuous movement of water through the environment; evaporation, transpiration, condensation, and precipitation
definition of water cycle
list 4 main processes in water cycle
-evaporation; the process in which a liquid changes into a gas or vapour
-transpiration; water from a plants root evaporates from the leaves, stem, and flowers from the plant
-condensation; the water vapour from the air changes back into tiny droplets of water when the air cools. Remain held in air as clouds or fogs
-precipitation; tiny water droplets from clouds unite to make large drops of drops. then these fall on earth as rain, sleet, snow, or hail.
