|
|
|
Transpiration
|
When water evaporates from plants during photosynthesis
|
|
|
Carbon and oxygen cycles
|
Animals take in oxygen and breath out carbon dioxide. Then the plants take the carbon and breath out oxygen
|
|
|
Nitrogen fixation
|
The process of changing free nitrogen gas into usable form of nitrogen.
|
|
|
Sublimation
|
When ice from a glacier turns into water vapor.
|
|
|
Decomposers
|
bacteria and fungi that break down waste and dead bodies.
|
|
|
Percolation
|
when water goes through the ground
|
|
|
Producers

How organisms are affected when something is removed from a food chain or web
|
There may be too many of them or they don't have any food. They might adapt.
|
|
|
Which layers in an underground system are permeable or impermeable and which layer is the saturated zone.
|
permeable, water can move through. Impermeable is opposite. Saturated is where water sits.
