*used to represent energy or matter in an ecosystem
*each level of a food chain or food web is called a **trophic level** |
|
|
Term
|
Definition
available at each traffic level.
* only 10% of the energy available within a trophic level is moved to organisms at the next trophic level.
*this small % shows how small the amount left is at the top |

Term
| recycling in the biosphere |
|
Definition
*remember, energy moves one-way in an ecosystem
*matter in an ecosystem is recycled within the system or between the systems
*matter is not used up it is charged
example: a molecule makes up a plant, an animal eats the plant,another eats the first animal and is digested into the system
*the original molecules never leaves it gets charged |

*all living things need water
*water moves between the ocean,air, and land in different forms |
|
|
Term
|
Definition
*the atmosphere contains water molecules in the form of vapor
*the process of water changing from a liquid to vapor is evaporation
* example: water evaporates from the ocean |
