1

Greenhouse effect consequences

-global warming
-ice caps melt
-flooding
-climate change/extreme weather
-habitat destruction
-extinction

2

Lightning

Converts N2 into nitrates

3

Nitrifying bacteria

Converts ammonia (in decaying matter) into nitrates

4

Nitrogen-fixing bacteria

Converts N2 into nitrogen compounds

5

Denitrifying bacteria

Converts nitrates into N2

6

Carbon dioxide (human activity)

-burning fossil fuels
-deforestation

7

Methane (human activity)

-rice growing
-cattle farting

8

CFCs (human activity)

-leaks from old fridges
-damage the ozone layer
-aerosol sprays

9

Deforestation

-leaching
-infertile soil
-soil erosion
-flooding
-more CO2 in the atmosphere
-local climate drier

10

Fish farming

-prevent using energy
-prevents interspecific predation (others)
-diet rich in protein
-separate young from big fish
-prevents intraspecific predation (same)
-biological control can be used
-selective breeding
-water monitored (O2, temp, pH)
-water can be filtered (remove faeces, avoids pollution)
