Ecology cycles Flashcards
What is a hydrological cycle?
The water cycle
What is transpiration?
Where water leaves forestation, evaporating.
What is throughflow?
Labelled underground, it is where water travels through soil
What is groundflow?
What which travels through the ground
What is interception?
Labelled below a forest - this is where water is drawn back up into a forest rather than travelling the sea.
What time of day does plants use carbon?
Day time - photosynthesis - intake
Night time - respiration - expells
What is the difference between decaying and fossilisation?
if the conditions are not right for decay i.e. pH, temperature, moisture ect the deceased matter will fosillise instead causing in million of years fossil fuel.
How much nitrogen is in the atmosphere?
78%
Why can we not breath in nitrogen?
Because it is a diatomic molecule which has a triple covalent bond.
How does the Nitrogen get broken down for plants and by what? Put another way how is Nitrogen gas converted to Ammonia?
Nitrogen Fixation which is created by Nitrifying Bacteria
As part of the cycle requires, how is nitrates returned back to nitrogen gas?
By Denitrifying bacteria.
