Nancy learned in school that composting is a way to cycle nutrients, and as tiny ecosystems, composting requires biotic and abiotic 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.
