Decomposition Flashcards
1
Q
What is the rate of decay?
A
speed in which matter is broken down
2
Q
how can we measure the rate?
A
changes in pH, mass or temperature
3
Q
What effects the rate of decay?
A
Temperature, oxygen availability, water
4
Q
How can we use waste?
A
In manure and compost
5
Q
What is anaerobic decay?
A
When bacteria and fungi break down a organism without oxygen
6
Q
What is biogas?
A
Energy created from the methane and carbon dioxide released when decay occurs
7
Q
How can we experiment decay?
A
Milk in warm temperatures, measuring the pH change as the bacteria within the milk carries out a process which causes the milk to become lower pH
