Answer:
1. water-to sustain condensation in the glass wall and to prevent wilting.
2,the layer of soil inside should be well mixed or replenished to reduce loss of microorganisms or to prevent microbia damages and to maintain good growing conditions.
They are abiotic or non-living resources,
if these resources were not replenish- no water would be available from condensation of evaporated water from the soil in the terrarium, and the plant will wither
If the soil is not mixed aeration will be poor, microorganisms will die,and good growing conditions will not be provided for growth.
Generally a saleable glass container or open glass container which contain plants growing on a layer of soil , which can be accessible for maintenance is called Terrarium.
The resource that can be replenished in the terrarium is water and it's an abiotic factor.
It should be noted that abiotic factors simply mean the non living components that are present in the ecosystem.
In this case, the resource that can be replenished in the terrarium is water and it's an abiotic factor. This implies that's it's a living component.
Lastly, if the resources aren't replaced, it'll lead to the death of organisms.
