Bio Flashcards
Give examples of abiotic envirment:
Water, soil, rock
What is the earths largest system?
The biosphere
This is the passage of energy in a one way direction through an ecosystem
Energy flow
This is living material
Biomass
The rate of an ecosystem which photosynthesis captures energy
Gross primary productivity (GPP)
Energy that remains as bio mass after plants an other producers carry out cellular respiration
Net primary productivity (NPP)
What is the most important gas of the carbon cycle?
Carbon dioxide
Explain the carbon cycle
Carbon enters plants as co2 which photosynthesis incorporates into organic molecules. Cellular respiration of the limestone return to co2, to the water and atmosphere, where it is then available to producers.
Give the 5 steps of the nitrogen cycle
Nitrogen fixation Nitrification Assimilation Ammonification Denitrification
Conversion of nitrogen gas to ammonia
Nitrogen fixation
Conversion of ammonia to nitrate
Nitrification
Conversion of organic nitrogen to ammonia
Anmonification
An exchange of water between the land, ocean , atmosphere and organisms
Hydrologic cycle
All absorbed solar energy is retaliated into space a what?
Infrared radiation
The tendency of moving air or water because of earths rotation, deflected to the right in north hemisphere and left in Southern Hemisphere
Coriolis effect
