|
|
Decomposer |
Organisms that break down the cells of dead or waste materials and absorb their nutrients |
|
|

Ecological footprint |
A calculation of the total area of land and water supply all of the materials and energy a human uses to absorb waste products |
|
|
How could you reduce your ecological footprint? |
- take the bus - walk to school - reuse bags - turn down the thermostats - eat locally produced foods |
|
|
Parasitism |
One is harmed and the other benefits |
|
|

Both organisms benefit |
|
|
Ex. Parasitism |
Lice and a head Tapeworm and a stomach |
|
|
Ex. Commensalism |
Orchid and the tree |
|
|
Ex. Mutualism |
Ants and aphids Bees and flowers |
|
|
Ecosystem |
Relationships between Abiotic and biotic |
|
|
Baseline data |
Information gathered by scientists to be used as a starting point to compare changes in the environment |
|
|
Food chain |
It shows how energy stored in food passes from organism to organism |
|
|
Food web |
It shows producers are usually eaten by many different consumers |
|
|
Biological control |
Controlling insect pests using their natural enemies You can do this with lady bugs |
|
|

|
|
Pollen |
The teeny particles of pollen containing sperm |
|
|
The three key points of the particle model |
- All substances are made of teeny particles too small to be seen - The particles are always in motion vibrating, rotating, ( and in liquids and gases ) moving from place to place - The particles have spaces between them |
|
|
Temperature |
Temperature is a measure of how hot or cold something it is measured on a scale it is the average connect energy intercept |
|
|
Heat |
Heat is thermal energy transferred from one object or substance to another because of a temperature difference |
|
|

A bio metallic strip is made of two different metals joined together. As they are heated one expands |
|
|
Convection |
A warm fluid moves from place to place through a fluid carrying thermal energy - Popcorn maker |
|
|
Conduction |
The process of transferring thermal energy to direct collisions between places - pot |
|
|
Radiation |
The transfer of energy without any movement of matter. Radiation energy behaves like waves it can be absorbed and reflected by objects - microwave |
|
|
Internal force |
A force that acts on an object from the inside |
|
|
External force |
Is steer that acts on a structure from the outside. Not part of the structure |
|
|
