Q

Define transpiration

A

Evaporation of water from plant leaves

17
Q

Define precipitation

A

Rain, snow, sleet falls or condenses on the ground

18
Q

Define subsurface runoff

A

Water/precipitation running over ground and into bodies of water

19
Q

What is a stomata

A 
Structure
releases water from leaf cell 
2 guard cells 
Loss of water through stomata called transpiration 
Plant take Carbon through stomata
20
Q

Cellular respiration

A

Plant and animal release energy from glucose
Release Carbon dioxide

Glucose + oxygen - Carbon dioxide + water

21
Q

What happens in the nitrogen cycle

A 
Nitrogen absorbed by plants 
Nitrogen into earth become nitrate 
Nitrate consumed by animals 
Animals death and decay 
Bacteria from animals 
Nitrogen back to atmosphere
22
Q

What happens in Carbon cycle

A

Absorbed by plants and animals
Fossil fuels
Ground level
Back to atmosphere

23
Q

What happens in water cycle

A

Evaporation
Condensation
Precipitation
