|
|
Term
|
Definition
| the amount of energy being transfered from one organism to another |
|
|
Term

|
|
Term
carbon-oxygen
nitrogen
water cycle |
|
Definition
|
|
Term
|
Definition
| Oxygen is released as a product of photosynthesis - organisms use oxygen for respiration - carbon dioxide is released by organisms - plants use carbon dioxide for photosynthesis. this cycle is ongoing. Carbon dioxide is also released during decomposition |
|
|
Term
|
Definition
| this part of the nitrogen cycle involves bacteria and some plant roots supplying fixed nitrogen for the plants needs |
|
|
Term
|
Definition
| this happens when animals eat plants and get nitrogen and then return nitrogen back to the soil through waste |
|
|
Term
|
Definition
| when organisms die, bacteria break down nitrogen compounds and release nitrogen back into the environment |
|
|
Term
|
Definition
| this changes nitrogen gas into a form that organisms can use |
|
|
Term
evaporation
transpiration
condensation
precipitation |
|
Definition
| 4 stages of the water cycle |
|
|
Term
|
Definition
| when liquid water turns to gas |
|
|
Term
|
Definition
| the process where plants lose water through their leaves |
|
|
Term
|
Definition
| when water gas combines and cools, it turns back to liquid |
|
|
Term
|
Definition
| when the cloud can no longer hold the water vapor. Can come down as rain, snow, sleet or hail |
|
|
Term
| respiration - cellular and breathing |
|

|
|
Term
|
Definition
| during decomposition ______________ & ______________ is released back into the environment |
|
|
Term
|
Definition
| two types of ecological succession |
|
|
Term
|
Definition
| no plants - pioneer species - a species that can withstand extreme conditions. i.e. lava flow, glaciers, sand dunes |
|
|
Term
| STAGE 1 of primary succession |
|
Definition
| rocks - lichen is the 1st to appear. the lichen will die and the acid breaks down the rock to form the first soil |
|
|
Term
| STAGE II of primary succession |
|
Definition
| small plants appear - mosses - fertile soil |
|
|
Term
| STAGE III of primary succession |
|
Definition
| grasses, wild flowers and small animals |
|
|
Term
| STAGE IV of primary succession |
|
Definition
| shrubs, small trees and larger animals |
|
|
Term
| STAGE V of primary succession |
|
Definition
large trees, mature forest
