Biochemical cycles Flashcards
(27 cards)
Transperation
Refers to water loss in plants
Evaporation
Loss of water from a lake or ocean
What is the hydrocolic cycle run by
Radient energy from the sun
What is the hydroholic cycle
Is the water cycle
What is a water molecule made of
2 H and one O
Which side of a water molecule negative
Top O
Which side of a water molecule is positive
The bottom H
Why is water the universal solvent
When it bonds to hydrogen it enables it to disolve items easily
What is the role of water in the biosphere
When water melts of rises or lowers it brinings along nutrients unlocking them and bringing them to various places.
Why is liquid water more dense than ice
When water is frozen it creates a flexable and stretched bonding
Cohesion
Hydrogen bonding causing water to bond to eachother
Adhesion
Attraction of water molecules to other substances
What causes water to dissolve substances
Hydrogen bonding
What is the most dense form of water
Liquid water since when frozen its bonds start to expand
What kind of heat capacity does water have
High
What does the stomata of a plant do in the case of a drought
Closes and becomes less active
What is the water cycles coloration when it comes to the other cycles
A big role
Is water vapour a greenhouse gas
Yes
What is a nutrient reservior
Biochemical cycle substances that are temporarily stored in nurtient resivors
Rapid cycling
Substances that cycle between resvirors quickly
Slow cycling
When susbstanes acumilate and are unavaliabe to organizums
What are major carbon sinks on the Earth
Trees/ ocean
Deforestation
Trees store large amounds of carbon and release it when cut
Burning of fossil fuels
Releases CO2 back into the enviroment
