Nancy learned in school that composting is a way to cycle nutrients, and as tiny ecosystems, composting requires biotic and abio
tic factors. She found four lists with ingredients to add to her compost in addition to the kitchen food scraps. List
Biotic factors
Abiotic factors
1
fungi
worms
water
sun
2
water
worms
rocks
light
3
worms
fungi
leaves
sun
4
water
sun
fungi
worms
Which list matches with the information she received in school and why are the ingredients a good choice?
A
List 1, because it has a balance between biotic decomposers and abiotic factors needed for the worms and composting.
B
List 2, because worms and water are the only biotic factors needed. Worms as decomposers, and the water for the worms to live.
C
List 3, because the abiotic decomposers, leaves and sun provide an excellent environment for worms and fungi to start composting.
D
List 4, because for the abiotic factors to decompose the kitchen scraps, they need plenty of water and sun.
List 1 is the best choice of materials because it has a balance between biotic decomposers and abiotic factors needed for the worms and composting.
<h3>What is composting?</h3>
Composting is the process whereby remains of organic matter are keep in a favorable environment and conditions in order to allow for decomposition.
Compost consists of the right mix of biotic factors suchas worms and fungi as well as abioticfactors such as water and sun.
Therefore, based in the materials provided, List 1, because it has a balance between biotic decomposers and abiotic factors needed for the worms and composting.
