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

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.

4 main process in the water cycle
definiton of precipitation
water that falls from the clouds towards the ground, especially as rain or snow
definition of evaporation
Evaporation is the process by which a liquid turns into a gas.
definition of transpiration
Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves
definition of condensation
the process by which water vapor in the air is changed into liquid water it’s the opposite of evaporation. Condensation is crucial to the water cycle because it is responsible for the formation of clouds

definition of run off
Runoff occurs when there is more water than land can absorb into lake and/or creeks

definition of bioaccumulation
the accumulation of pollutants in organisms through the levels of the food chain, so that organisms higher up in the food have higher levels of pollutant
