|
Food chain |
- shows the way energy gets transferred from one living thing to another through food. •producers- organisms that make food for themselves( plants) •consumers- organisms that eat something else( herbivores+ carnivores) |
|
|
Food web |
- consists of many food chains - a food chain just follows one path as animals find food, food web shows how many different paths are connected together |
|
|
Photosynthesis |
The process used by plants in which energy from the sunlight is converted to glucose - the glucose is used by the plant for energy( through respiration).
Sunlight/ chlorophyll Carbon dioxide+ water---- glucose +Oxygen |
|
|
Respiration |
- all of our important life processes need energy - respiration is the process our bodies use to produce energy Glucose+ oxygen----- water +carbon dioxide+ energy |
|
|
Aerobic + Anaerobic |
Aerobic- respiration with the presence of oxygen Anaerobic- respiration without oxygen |
|
|
Energy cycles of a food chain |
- transfer of energy from one organism to another - 10% energy passed each trophic level |
|
|
Carbon cycle within food chain |
-Carbon dioxide absorbed by plants during photosynthesis - animals eat plants, pass carbon compounds - animals eat animals - animals give off carbon dioxide during respiration |
|
|
Nitrogen cycle within food chain |
- plants absorb nitrogen through roots - animals eat plants, nitrogen passed through the food chain - nitrogen released into soil by decomposers when animal dies |
|
|
La Nina |
- cooling of water in the Pacific ocean - trade winds strengthen -causes greater rainfall and flooding |
|
|
El Nino |
- warming of water in the Pacific ocean - causes warm weather and droughts |
|
|
Greenhouse effect |
Effect of green house gases in the atmosphere trapping solar energy, helping retain heat on earth |
|
|
Ozone layer |
- is molecule made of three oxygen atoms - it's a layer in our atmosphere with lots of ozone molecules - it's been depleted by the CFC's that used to be in spray cans, destroying the ozone layer by creating a hole |
