Answer:
Availability of soil minerals
Step-by-step explanation:
Abiotic factors are the non-living factors in the ecosystem. These materials are the chemical and physical components of the ecosystem. They are not biological in nature.
- Soil minerals are abiotic since they are produced from rocks.
- Invasive weed species, animals pollinating and disease causing fungal spores are all biotic.
- They stem from biological processes.
